Hi Craig I have resolved the related spec bug you filed
https://www.w3.org/Bugs/Public/show_bug.cgi?id=26418

Mike - the addition of the implied roles for <th scope=col> and <th
scope=row> clarify that the presence of aria-sort on either does not need
to be used in conjunction with any aria roles when used on <th scope=col>
or <th scope=row>. Can you modify the validator conformance checking to
reflect this?
