The form for age 3.11 is normed up through age 8.11. The form that is normed through age 17.11 begins with age 5.0 norms. They are both the same edition. I would have thought that she did give the form designed for his age group, but since it has items for nearly nine-year-olds, and he would have started from the first item, it could still take longer than usual, if she had to give every item.
OTOH, no manipulatives? There should have been colored blocks or foam pieces, for one subtest, and various small toys or colored chips, for another subtest. (The colored blocks would apply to either the early years or school-age form. Unless she skipped the spatial cluster altogether, as being the least correlated with giftedness.) If you really didn't have any manipulatives, I would suspect that she administered the school-age form, which really only has norms down to age 5.0. In that case, the GCA is a low estimate, as your child is over a year younger than the lowest age norm group.
