Seems like a bug to me. Certain branches in _array_richcompare return False to fail rather than Py_NotImplemented, which means the string-understanding comparison fallbacks don't run. Attached is a (simple) patch that resolves this bug, and doesn't seem to cause any of the unit tests to fail. Does this make sense to someone with a better understanding of the rich comparison code than I?

Could you open a ticket for this and mark it for review?
Here's the ticket: http://projects.scipy.org/numpy/ticket/1491 Mike, could you attach your fix?
