What version of CPAN/Perl do you have? (The code shown above belongs to what ships with Perl 5.12.2 — older versions had rather different code...)
Update: just checked that the CPAN which shipped with Perl 5.10.1 (v1.9402) looked very much the same, so yours must be older. For example, with Perl 5.8.8, the respective code read just:
@nums = split (' ', $num);
my $i = scalar @$items;
(warn "invalid items entered, try again\n"), next
if grep (/\D/ || $_ < 1 || $_ > $i, @nums);
