Thanks for the reply.

I guess the more basis question is one of canonical order.  Functions
(like Times) that are attributed with Orderless reorder their arguments
according to some form of canonicalisation.  In my case I have a
data-type where I have a different idea of the canonical than mathmatica
has and I was wondering how to influence mathematica in deciding when
things are canonical.  Is this possible?
