Yep.
My school actually came first in the state for standard English last year, and being such a mathematical/sciency school, a lot of people were able to get 95+ for the UAI. One, because they got really good in standard English (we're talking 80+, top 2% of state) and because their maths (ext 1, ext 2) got them over the 98 barrier.
So definitely - if you do well in those high scalers you have, then 95+ is very possible.
