Believe it, it's true -- they use a Z-Buffer for the Alias Models.
There are a *multitude* of sorting problems that cannot be solved with
Z-based sorting. In *very* simple cases, you could take the "average" Z
of a given polygon and sort based on that, however with the models that
they have, many polygons interesect and overlap many other polygons
(both within the same model, and otherwise).
BTW, If you're not having these problems with your displayer, try
looking at a different model...Many of them will exhibit the sorting
errors.
