Fix for bug #28748: "Select" returning one value too few

Browse Source 
Problem: we may get unexpected results comparing [u]longlong values as doubles.
Fix: adjust the test to use integer comparators.
Note: it's not a real fix, we have to implement some new comparators 
to completely solve the original problem (see my comment in the bug report).
