When used on arrays with ndim >= 2, and without argument is given, Array.sort_values combines axes, while Array.labelsofsorted and Array.indicesofsorted both raise an Exception. FWIW, numpy uses the last axis (axis=1) in those cases.
We discussed this in #225 but never actually done anything about this AFAIK.
From the discussion in #225, I guess we should combine axes by default in labelsofsorted and indicesofsorted. The other option is to make all three methods use the last axis by default.
