Write your own comparator, or compare something like
sorted(items(obj)). It's intentional that MochiKit doesn't define a
comparator for arbitrary objects that it doesn't know anything about.

MochiKit doesn't currently implement anything like that.

I doubt you'd really want to use much from MochiKit to implement that,
other than compare. It's pretty basic stuff otherwise.
