Test case: steps in the tutorial, up to the frequency table by filename. The results table is unsorted, even though it was sorted by Frequency for the previous query. If Frequency is selected as a sorting column, it appears as "Frequency(2)", indicating that the previous sorter is still around somewhere, but is not applied.
The reason is probably that the ID of the Frequency function is different, and therefore the sorter doesn't find the corresponding column. However, it is not discarded; probably it should.
