Ok, as I often do, I think I've sort of answered my own question - thank you google books previews!

It looks like the visuomotor precision test was sort of a handwriting-type test... find motor control, which we knew was not good, and had gotten worse after he started one of his meds. We've been trying to work on that this summer, and it actually seems better now - he's started drawing again - woo!
