Following-up myself and after looking at this again, I think there is no
way to make it all work within font-latex.el.  I think the best way is
to patch font-latex.el in order to understand optional arguments after
verbatim macros (delimited or with braces) like this:

Style files like minted.el can add their special requirements to
`font-latex-syntactic-keywords-extra'.  The result can look like this:

Description: PNG image

The entire patch is attached.

font-lock.diff
Description: Text Data

The questions remaining are:
1)  Should user defined macros like \perlinline be fontified like
    \newmintinline?

2)  If yes, should \verb be fontified as well?

Any comments welcome.
