"greater than" comparison method of doesn't perform as expected on Micro objects

[cpcloud]

Using IPython:

In [1]: import pandas

In [2]: Micro = pandas.datetools.Micro

In [3]: 3 * Micro() > 2 * Micro()
Out[3]: False

In [4]: 2 * Micro() > 3 * Micro()
Out[4]: False

They can't both be False. Giving the arguments to > to cmp works as expected. Not sure where the issue lies since neither Micro nor any of its superclasses implements any of the comparison methods except __eq__ and __ne__.
