What concerns me is that, obviously, the size of the files left out is summed up nevertheless (this is what I could not test over here). Please try this modification and report back:

Code:
                if (T[1] == KnownTime)  {print "echo rm " LastFile

                                         print SUM += $2 * $3
                                         if (SUM >= Needed) exit
                                        }
