I see. This is not a bug. It *was* a bug in R < 2.3.0 and has been
fixed. From NEWS:
o sort() now does not return inappropriate attributes such as
"dim" and "tsp": it only returns names.
You cannot expect sort to do anything meaningful when applied to
matrices or arrays other than returning a sorted vector of the elements,
and that is what sort does nowadays.
