Never used it but looking at the source I'm not sure that it'll do what you want. Your second argument is getting passed in as $replace into this bit of code: 

  else {
    @content = split( /\n/, cat($file) );
    for (@content) {
      s/$search/$replace/;
    }
  }

You've tried to quote things correctly, but for that to work there'd need to be an /ee modifier on the substitution to get it evaluate the contents of $replace and then replace with what that expanded text contains. Unless there's some new dark magic I'm not aware of for expansions that lets you turn on /ee at a distance I don't think it's capable of what you're trying to do.

Edit: Aah you've got the multiline option set; the substitution would be the similar s///mgs a few lines earlier but the problem remains the same (it'd need to be s///mgsee to expand $replace and then evaluate the expanded value).
