Possibly the next step (after col, colgroup, thead and tfoot) is to look at
elements around it. I'd hazard a guess that if there's table data in the
same row, either immediately before or immediately after the th, then the
scope of the header could be row. If there's table data in the corresponding
cell on the previous or next row, then the scope may be col.

There are probably quite a few exceptions to these pointers.

Seems that way :(

I don't believe there's anything further defined after scope header and id
attributes. Although there's still the colgroup / col elements that could
allow grouping. Correspondingly, the thead and tbody give inklings to col
type scopes.
