    I thought SXHASH was changed ages ago so
     (not (= (sxhash '(a b)) (sxhash '(b a))))

I believe what was decided was that it was unreasonable to suddenly change the
behavior of SXHASH because of the danger of screwing people with SXHASHes
recorded in files.  Thus a switch was installed to allow the user to choose
between the old behavior and the new, and the default was made to be the old.
Doing (sstatus sxhash nil) will turn on the new behavior which has the property
you are looking for.

Someday the new behavior may become the default, but I wouldn't hold my breath.
