I think John's point was more that scope is something rather specific to an OAuth access token and, while JWT is can be used to represent an access token, it's not the only application of JWT. The 'standard' claims in JWT are those that are believed (right or wrong) to be widely applicable across different applications of JWT. One could argue about it but scope is probably not one of those.
It would probably make sense to try and build a profile of JWT specifically for OAuth access tokens (though I suspect there are some turtles and dragons in there), which might be the appropriate place to define/register a scope claim.
