I usually think of the margin of error for Benchmark as about 10%. Any difference smaller than that is likely to be noise. This might also be a case where you move the code from place to place in the file and it changes speed (see No More Meaningless Benchmarks!).

Or maybe it's faster to say {$a<=>$b} rather than {$b<=>$a} for some reason. If I run your benchmark, changing only reverse sort to sort (so the 'reversed' case actually sorts forward), the results look about the same—{$a<=>$b} wins.

In any case, I'll probably keep thinking of them as "the same speed", benchmarks be damned.
