If your US-based schools are requiring 130 on achievement testing as well as ability testing for GT placement, you may be able to sidestep that by providing the psych report. It should include, at a minimum, formal diagnoses of dysgraphia and dyspraxia, and a statement that indicates that the FSIQ is invalid due to the discrepant WMI and PSI, and that the GAI should be used as the more accurate estimate of his intellectual functioning, and a statement that his significantly discrepant and relatively poor performance on the achievement testing is a reflection of his impairments in motor output and attention or working memory.
Here in the states, your child would certainly meet the criteria for a 504 plan, if not an IEP, and pointing out that the paper and pencil testing is not truly accessible to your child without accommodations, as it is your child's disabilities that interfere with his output on this testing, should be one way to get him the services that he will need. He cannot, in theory, at least, be denied access to gifted programming on the basis of his disabilities, and the GT program would be required to allow him to have whatever reasonable accommodations are necessary for him to have equal access to the program, such as a keyboard and extended time on tests.
