What is the IQ of a Gorilla and what can it do? How many words can one remember?

Hmmm,
Here are a couple of notes about a gorilla named Koko.

As a juvenile, they're rating the IQ at 95, and as an adult, in the 80's and 90's (I think).
It says Koko's vocabulary (sign language) is around 1000 words.
On a slightly different track, apparently a dog, Chaser recognizes the names of about 1000 different toys, (http://abcnews.go.com/Technology/world-smartest-dog-nova-special-shows-border-collie/story?id=12875750) and can even deduce the name of a new toy, Darwin.
Anyway, I would imagine that doing interspecies IQ tests would be difficult. Did they skip any questions? Addition, subtraction, multiplication, division, differentials, integration? Apparently Koko doesn't do math (http://koko.org/kidsclub/ask/), so how actually was that section of the IQ test scored? What about inference? A is to B as C is to D? Many IQ tests do inference questions both verbally and graphically. 1000 words? Was the IQ test tailored to the gorilla's vocabulary?
