I decided the quote syntax for perl-mode, so I'm biased.  But in any case
word-syntax for $ is wrong, just like it is wrong for _ or - or any other
non-alphabetic char.  Strangely, tho, $ has word syntax in fundamental mode
(which is from where sh-script inherits it, oddly enough).  Shouldn't it be
changed to quote syntax or symbol syntax (in fundamental-mode)?

In general, in Perl, $ plays many different roles and it should sometimes
have word/symbol/quote syntax, sometimes have escape syntax, perl-mode and
cperl-mode chose different defaults, and then tweak them on a case by case
basis with font-lock-syntactic-keywords.
