Although this is outdated,take a look at http://alpha.fdu.edu/psychology/kbitwisc.htm
to get some idea of how folks go about answering the question - does the KBIT screener correlate to an IQ test?

Then there is the question of 'How good are IQ tests at measuring IQ when the subject is unusually gifted?' It has been considered that around 99.8 most tests start to lose meaning.

Are these scores good? That sort of depends on what you were expecting? Depending on the local expectations, folks at the 90% can start feeling like they are always going to be the smartest folks in the room. On the other hand, I'll bet you've heard plenty of stories about kids feeling mighty stupid when they get to places like MIT. There isn't any 'approved' definition of gifted, or of any of the levels of giftedness.

If you can say more about what you might hope to gain by testing, we can ask better questions to help you think about 'what's it worth to ya?'
