Still, can you name any Wizards of the Coast prestige classes that use ability score requirements?
Since I don't have all their books, no. And of course, they probably don't use any PRC's with ability score requirements

Nonetheless, I don't think this invalidates their use in an appropriate PrC. After all, people have used all sorts of different prereq's, including many in 3rd party publishers that WotC haven't used, and I don't think that attributes as prereqs is in any way out of line.
Now, if for no good reason you just arbitrarily decided that a PrC needed str 12, dex 13, and int 17, but without much reasoning, that's a bit off - btu for, say, a prc for a god of might, it would reasonable to have a str requirement.
