One idea is to do it like WebKit's SunSpider runner script (Perl): run
each test 5 times (I know it may take a long time) and find out the
95% confidence interval. If it is beyond a certain threshold, e.g. > 5
%, then mark the test as "not confident enough". Thus, only comparing
two confident outcomes will be more or less conclusive.
