You'll need a strut or invisible box of some sort to make the box for  
the ``a'' as tall as that for the ``b'' --- probably the best thing  
to do is to define a macro which takes three arguments, e.g.:

$x^a_b$ $x^b_a$ $\supersub{x}{a}{b}$ $\supersub{x}{b}{a}$

I believe.

I'd suggest checking out Gratzer's Math Into LaTeX to be sure of a  
good answer though.
