Have you spoken to someone at Scottish Disability Sports? If they understood the full package of problems then they might see things differently. It may be that they don't count autism on its own but it sounds as though he has ample other problems that should count in their eyes.
I wondered whether tandem cycling might work with him? If he took the stoker role at the back with someone as pilot on the front. Perhaps you could try this out on a tourer and then think about trying a racer later on?
