How old was Milo when you brought him home and have you checked in with his breeder for advice? I don't think you've done anything wrong, more likely it is what you haven't done ... take charge and be the alpha leader. It isn't too late, you aren't a failure or a bad owner, just fallen into what many of do with puppies. Some puppies from the beginning need firm rules, structure and discipline and a stronger hand than others do. Milo sounds like he's one of those and needs a figurative knot jerked into his little bunny bum. Emplementing Nothing In Life is Free (NILIF) training with him now would be a very good idea.

While play biting is a given part of puppyhood, it is never an okay behavior and humans should never be chew toys.

His bad behaviour almost always started in the afternoon and during the time I take him out to the backyard (to relieve himself). For the past week, after he was done, he would take one look at me and jump for my pants and chomp as hard as he could. Any attempt to stop him (either by keeping still, holding him down or redirecting him) was rewarded by bite marks and torn sleeves.

Milo has created a game, set the rules and is controlling all play. He's in charge. I don't think a metal choker/chocker collar is necessarily in order, a martingale style collar, nylon choke could be used in the same fashion and used for the same type correction Michael is recommending. The same message could also be sent with a regular flat buckle collar and a leash. When you let him out for his afternoon potty session, attach his leash to his collar and just let him go about his business dragging the leash. When he finishes and gives you the look that it is "game" time, step on the leash. This will give *YOU* control of the situation; pick up the leash and bring him in. Other things you can do are - get a pair of heavy weight garden/work gloves (if you are concerned about your hands getting chewed on), pick him up when he comes in for the attack (your foot on the leash will prevent him from playing catch me if you can), and flip him over on his back like cradling a baby. He'll most likely squiggle and squirm and fight, but hold him firmly until he settles down (and you can use "settle" as a command here). When he calms down, give him a nice tummy rub and tell him good boy. Three things this does - one, establishes you in a higher dominance position, secondly, every corgi should enjoy a nice tummy rub and third, when vet visits are necessary, it makes him more accepting of exams and makes things less stressful all way around.

By then I would run back to the house (with him chasing and trying to bite me) and closes the screen door. Normally it would take 3 tries and time-out to cool him down. Then when I allow him to enter the house, he would return to his sweet self. It's frustrating... any advise would be greatly appreciated.

As I said, Milo's set the rules and is in charge of this game. NEVER run away from him in situations like this. IF you have to walk away, do so ignoring him and eyes ahead, back straight. Bratty puppies acting like jerks don't get attention and even negative attention is still attention. It also sounds like he has a lot of pent up energy he needs to expend at this time of day. So instead of spending all the time playing his game, try throwing sticks or balls or even the rope toys Michael suggested for him and let him run after them. Milo is one I definitely would NOT recommend or suggest tug of war type games with; his bite inhibition has already crossed a line you don't want and that could serve to make it worse. Walks would also be a good idea as has been mentioned - get rid of some of that energy. I'd also recommend getting him into obedience classes as soon as possible.

Btw, is there any correlation to his somewhat aggressive play with other pups and his over excited reaction towards strangers? with this burst of violent behaviour?

Not necessarily. Milo sounds like something of a dominant personality and he's exploring what he can and can't get away with with humans and with other dogs too. This behavior is something that does need to be addressed and gotten in hand and the sooner the better.
