This was posted on slashdot.org on saturday. I scored 42 ms (using speakers, at 11PM) when i tried it. I'd be interested to hear what other people get and how much they think it correlates with their success/intelligence (two different things, mind you) in life. I don't think that merely being able to differentiate between pitch tones well makes a person necessarily successful/intelligent. If the test is accurate however it could tell us the difference between those who can listen and interpret others' speeches well and those who cannot.
Anyway, post your age/score/relevant info.
(PS- I'm a 16/M/Caucasian)
