I think these things should give you points just for taking the test in the first place.
Think about it. How many non-geeks would take a geek test? None! Because they know they're not geeks and don't feel the need to be told so. Geeks, on the other hand, would love to know just HOW geeky they are.
It's also a true sign of geekiness when people lament their *low* scores. This kind of thing is taken care of very nicely in another very long but very amusing quiz:

My personal opinion is that you should give yourself extra points if you found the test funny or amusing (which I did). Enjoy.
(BTW, last I checked I was about 26%-ish)
