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

?
