a) yes.

b) well:

   The value of the scope parameter is expressed as a list of space-
   delimited, case sensitive strings.  The strings are defined by the
   authorization server.  If the value contains multiple space-delimited
   strings, their order does not matter, and each string adds an
   additional access range to the requested scope.

That certainly implies that you can't have a space inside a token, but it could be clearer.

Optimally, state the character repertoire precisely:

  scopetokenchar =  %x21 / %x23-5B / %x5D-7E
  ; HTTPbis P1 qdtext except whitespace, restricted to US-ASCII

?
