Initializing $count as a numeric string with a bunch of leading zeros will see the leading zeros vanish after the first numeric operation 'numifies' the scalar even if it's an operation with zero!

So do not numify it but use Perl's little quirks to do the trick:

perl -wMstrict -le 'my $count = "00000000"; print qq{"$count"}; ++$count for 1 .. 42; print qq{"$count"};'
