this is because of a different 'sort' default on redhat 7.x than the
previous versions. the earlier versions switched on -s (stable output) by
default, the new one does not. the test script depends on it to produce
the right validate results.

you can make the validation tests pass by turning on -s where sort is used
in the validation scripts, but i recommend you not worry about it if other
tests passed.

the reordering does not effect your simulation results.
