I looked at the code and in the end the values get propagated into calls to
MatSetValuesLocal() which does not require sorted values.
Thus my conclusion is that you do not have to sorted column indices in these
calls

Yes we do a nonexistent job of indicating when indices
I'm pretty confident all the tests are sorted. It wouldn't be any great
hardship for us to allow unsorted input. If you submit an unsorted
test, we can make sure it works (it might already, but we should
probably add a call to in-place sort).
