in thread Calculating/adding byte counts of array elements

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"};'
