His reported score is not valid.
If the difference between the highest and lowest subtest scaled score in an index (in this case VCI, verbal comprehension index) is 5 or more, then the index is not "unitary" and thus not "interpretable". See �Essentials of WISC-IV Assessment� by Dawn P. Flanagan, Alan S.Kaufman (the bible for how to interpret WISC-IV scores)

(or google '�Essentials of WISC-IV Assessment� interpretable' and see page 134)
So, neither the GAI nor the FSIQ (both of which include the VCI) should be reported. I'd say substituting the "information" score would give a better understanding, though I know they're only supposed to use that if it's decided before testing begins (I think an area of known weakness could justify this) or something interferes with the test session. So, it also may not be a reportable score, but will give better insight to his abilities than the invalid scores.
