The attached patch fixes this behavior, however I haven't committed it
because I fear it would undo some of Achim's intentions in commit
ca125b82b.  I'll leave the final solution to Achim.

Thanks for pointing this out,

Subject: [PATCH] print Perl variables with a format string

Thanks to Rick Frankel for pointing this out.

* lisp/ob-perl.el (org-babel-perl--var-to-perl): Print Perl variables
  with a format string.
