DBD::Sybase uses ct-lib.  From your description, it would appear that
there's a ct-lib function that returns the correct rowcount for TDS 4.2
and not for TDS 7.0.  (The protocol includes a status bit that indicates
whether or not the rowcount is valid.  That might not be percolated up to
the ct-lib API correctly in some cases.) 

If we can figure out which ct-lib function is telling DBD::Sybase the
rowcount is unavailable, we can see if in fact is *is* available and, if
so, fix it.
