Scar doesn't cut it as H=V

Why should Harry's scar make him Voldemort's chosen one? I can't see 
how the fact that Voldemort's curse failed means that V has chosen 
Harry as his Nemesis? 
I CAN see, though, Voldemort's choosing Harry (and rejecting 
Wormtail's suggestions that any wizard would do - not a witch, then?) 
for the blood part of V's restoration to corporeal status being the 
choice. I know it seems to come to the same thing, but I wonder if it 
does..
