__cmp__ is gone in Python 3 see [1]. The way to implement comparisons wil be through the various __lt__, __eq__, etc. There is already a ticket opened for dealing with that in #16537. It would be better to think about a solution that takes this into account. I do not know the Cython way.
There is another very good thing in Python3: you are "allowed" to raise a TypeError when the object are incomparable.
