integer and string compare, is that correct?

The behavior of disparate types being comparable is deprecated and has
been removed in Python 3.0+; don't rely upon it. (The ordering used is
arbitrary but consistent)
IIRC, the feature existed in prior versions to make lists containing
mixed types sortable; this was found to be not all that useful and to
hide what are quite arguably errors.

Cheers,
Chris
