I'm perfectly willing to explicitly convert the blank strings to 0. Is this the easiest way:

@arr1 = map {$_ eq "" ? 0 : $_} @arr1;

The blank strings are the only strings that cause a problem:

use strict;
use warnings;
use 5.010;

say '1' + '2';

--output:--
3

Why will perl silently convert non-blank strings to integers, but resist converting a blank string to 0? After all, perl converts a blank string to false in a boolean context. It seems like it would be a natural thing for perl to convert a blank string to 0 in a numeric operation.
