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.
