I think there is actually a bug here:

In [61]: sort(array([3,2], dtype=object))
Out[61]: array([2, 3], dtype=object)

In [62]: argmax(array([2,3], dtype=object))
Out[62]: 0

See, the sort works fine. I suspect argmax is using the wrong comparison
function. I was just pointing out that sometimes it is hard to know what is
going on with objects.
