Just an observation. Dont know how this will help or hurt you situation. Anytime you have an unquoted numeric that begins with a zero, it is interpreted as an octal:

{
    my $x = 10;
    my $y = 010;

    print "x = $x\n";
    print "y = $y\n";
}

Outputs:
x =10
y =8

But since you're using 00, that should interpret as numeric zero anyway, so im not sure whats happening.

Thought it might help someone else figure out the whole deal.
