The following issue still exists in Mathematica 9.0.1:
In: Ordering[{0, 0}, 2][[2]]
Out: 2
In: Ordering[{0, 0}, -1][[-1]]
Out: 2
In: Ordering[{0, 0}, 2, OrderedQ[{#1, #2}] &][[2]]
Out: 2
In: Ordering[{0, 0}, -1, OrderedQ[{#1, #2}] &][[-1]]
Out: 1
All of the examples should return 2, since they are functionally
equivalent according to the documentation.
