I for one would expect that selector to match that element, although I would never write HTML like that. Imagine a browser or user stylesheet where you would effectively have to list all possible casings.
That is, I expect attribute values that are predefined keywords to match no matter how I case them, because they are semantic – well, ‘center’ not so much –, but arbitrary strings should be case-insensitive unless specified otherwise (which is not possible in Selectors 3).

How about “[align="center"]” being case-sensitive and “[align=center]” being case-agnostic? ;)
