Font name modifiers such as /S that affect the actual font loaded need 
to be specified *before* optional features such as +onum. Your code 
would expand to a command like
	\font\dsp = "Brioso Pro:+onum/S=14" ....
but here the /S will be ignored, because it is seen as part of the 
feature string, not part of the font face name.

Yes, I know, the documentation could be a lot clearer about this 
stuff........
