I am not at all familiar with the UNIT but did want to say that his PRI score on the WISC is highly gifted and I'd push on that. 139 should be about the 99.5th percentile which is in line with the UNIT. I'd see what tests they do consider valid.
Would they consider the Raven? It's a group test, but based on the strengths he is showing in math and visual spatial, I bet that he'd do quite well on that. What is their protocol for identification of English Language Learners (ELLs) for gifted programming?
Were they the ones who gave him the UNIT? If so, why did they administer a test they don't consider a valid IQ test?? Actually, I'd say that the WISC isn't a true and valid measure of his IQ b/c the discrepencies are so large btwn subtests that neither the FSIQ nor the GAI is considered fully valid.
