Another thing: it was well established that Scar is physically small and very weak. Simba had a hard time defeating Scar, and size-wise, they were roughly the same. Nor did Simba have a full mane when he came back. He was near the end of his growing period, but not yet a full adult. So I would say he is about five years old. (20 or so in human years).
Also, while Simba didn't exactly know how to fight (I doubt that Timon and Pumbaa taught him how), I don't think that Scar was any good either. Scar was very lazy, and he had his hyenas do all the muscle work. If anything, Scar should have been a push-over. By the fact that he wasn't, it just go to show even more how young and inexperienced Simba was when he finally returned.
