Actually, now that I think about it, if this Zorro guy is a good guy then Jack cant do anything to him since his sword can't cut people with good hearts or something like that. It can only hurt evil people so maybe the Zorro guy would win.

Zoro is a pirate and a criminal. That's probably just enough for the sword to effect him. Even if it doesn't, Jack could still club him with it like it's a reverse-blade sword.
