Lemme just repaste from the report: "Comparing the scores via the GB3 links, show this score is faster across most sub-tests. There is not one (or other) sub-test that is massively out of line." So it is unlikely to have bugged. It would have had to bugged the timer pretty crazily to get such a big boost.
Edit: Although, I haven't looked at the other Intel GB4 scores, so maybe it is out of line.
