In your function, $FmtPV hasn't been made a global, so you end up
creating a local variable with $FmtPV['$price'] = "$price"; that goes
out of scope at the end of the function.

However, on a more meta-level you do seem to be re-implementing the
functionality of pagetext variables. What I think Hans was asking
wasn't why you weren't outputting PTV markup from your function, but
rather asking why you're trying to create a custom (:setpv ...:) when
(:ptv:value:) would work just as well?

And if you're set on creating your own function, I'd recommend looking
at adding an entry to $PageTextVarPatterns like '/(\\(: *setpw
+(\\w[-\\w]*) *=(?!\\))\\s?)(.*?)(:\\))/s'.
