You should probably get into the habit of avoiding the interpolation of unchecked variables directly into the format string of (s)printf (as with $l and $j here) as a general rule - there has been some concern over the last few years about Format String vulnerabilities, and whilst it is not a flaw in Perl itself the underlying C libraries could potentially be vulnerable.
