Unfortunately, for many releases, the list's sort algorithm would not
provide that property. Release for release, new cases where found where
the builtin ordering was not transitive (i.e. you get a < b and b < c,
but not a < c). With funny definitions of __cmp__ in some classes, you
can still get this today.
