Harry's got the Cruciatus and Imperius Curses, even if he doesn't use Avada Kedavra. Anyways, if this battle occurred before the Battle of Hogwarts, Harry could set a Basilisk on Percy. Oh, wait, I forgot another lethal spell Harry's got: Sectumsempra. I personally think it would be quicker to mutter an incantation and cause serious injuries rather than slicing incessantly and fruitlessly with a sword that can't even touch your enemy.
