Does this mean you'd get a different score if test is taken in a different language? Try taking a different IQ test in each language you know.
Then there's color blindness and other factors not necessarily taken into consideration.

My Portuguese and French is not up to snuff. For example, it takes me 15 to 20 minutes to sync in on French films, and probably 30 minutes to sync in to a soccer game, because their lingo is impossible, and they go way too fast. There is no Vin Scully here at all to color the game for you!
I'm not color blind, but after 3 right eye operations, I see double a lot, and those "drawings" are too small for me to be able to see them right, and it becomes a guess, which is not what the IQ test is really about. The "logical" sequencing is not complete, as there are parts missing in those as well, so the "result" for the score is an "assumption" and that has nothing to do with IQ, or intelligence, as it does with some luck in the answer.
The main issue with some of these "tests" is that they are generic, as are many "academic" designs, and they tend to manipulate things so that the details that are too far to one direction are usually taken out and not counted. The IQ test, does the same thing, since it does not acknowledge the logic, and assumes that its logic is the right one. It's OK for numbers and language, but not OK for visualization, which is not mathematical at all.
