Issue Summary

When attempting to sort the results of the Task report macro, The macro re-orders the results, however the results are not actually sorted by assignee. This can result in some tasks assigned to a given assignee being separated by other tasks not assigned to that user.
(see example images below)

In addition, the sort does not provide different results between ascending and Descending sort.

Steps to Reproduce

1. Create at least one page with a number of tasks using multiple different users for the tasks and providing a good mix of both tasks with users, without users, with dates, without dates, etc.
2. On another page, create a task report macro to report on the users.
3. Click the "Assignee" header to sort the column
4. if the results appear to be sorted, go back to the page and add more tasks for at least one user that has already been given tasks, then reload the page with the report macro and sort again. You may end up with unsorted results.
5. Next try to reverse the sort by clicking the "Assignee" header to change the sort order.

Expected Results

The results of the macro are sorted and ordered correctly

Actual Results

The results are not ordered or sorted, though the sorting and ordering is changed in some way that appears to be random but the ordering and sorting is consistent.

Workaround

Currently, there is no known workaround.
