I added an example of this class here:

To reverse the values, it looks like to me that you'd just have to
create the keyArray like this:

for(vtkIdType i = valueArray->GetNumberOfTuples() - 1; i >= 0; --i)

(That is, just create a list of reverse-ordered integers, like 5 4 3 2
1 0 to reverse the elements in an array with 6 values).
