My best guess from looking at the code (I haven't tested it) is that
it will try to fulfil the request on the "wrong" kind of CF, but I
don't think it actually handles that case correctly.

If you could verify that there is a bug here and file a JIRA ticket if
so, that would be helpful. :)

Right -- currently supercolumns are always name-sorted, and their
subcolumns are always time-sorted.
