Those are very high scores but determining what he'll need really depends on the personality and temperament of the individual. The difference between people who test in the same percentile can still be pretty dramatic. Some kids in this percentile need radical acceleration, may end up in college at a young age. Others do well homeschooling, unschooling. Some find their place in specialty schools. Some do great in more traditional schools that can offer the individual a lot of flexibility.
Your best bet it to research all your options. Pay attention to how your child is handling different environments and what they seem to particularly want in and educational environment. Do what works best in the present and don't stress about the future too much. What your child wants and needs will change as they grow.
