I was surprised by my $total += $_->{COMP_TOTAL} for @pe_total; so I ran the code. No output generated so I modified the print to print "$^V >$total<"; which prints:

v5.16.3 ><

What is different about the way you are running the sample code? Different Perl verion maybe?

The B::Deparse of the summing line is:

(my $total += $$_{'COMP_TOTAL'}) foreach (@pe_total);

but my Perl foo isn't strong enough to decide if that means $total is local to the loop body or not. The result implies that it is, at least for this version of Perl.

Perl is the programming world's equivalent of English
