Both of my children score substantially lower on the CogAT (which I assume is similar to the OLSAT) than on the WISC IV.
Another thing to consider: Do you think it's possible that your younger daughter might have an undiagnosed learning disability?
I finally got serious about figuring out if my older son (then age 8) was actually 2E rather than simply average with slow processing speed when my younger son started reading at age 2. Several years later the older one was diagnosed with dyslexia and determined to be HGish.
