you might not actually want to do it this way, but:

use strict;
use warnings;

my @array_1 = (1, 12, 34, 50);
my @array_2 = (1, 1234, 50);
my @array_3 = (34, 12, 1, 50);

for ([\@array_1, \@array_2], [\@array_1, \@array_3]) {
    if ("@{[sort @{$_->[0]}]}" eq "@{[sort @{$_->[1]}]}") {
        print "match: [@{$_->[0]}], [@{$_->[1]}]\n";
    } else {
        print "mismatch: [@{$_->[0]}], [@{$_->[1]}]\n";
    }
}

Prints:

mismatch: [1 12 34 50], [1 1234 50]
match: [1 12 34 50], [34 12 1 50]

where the magic of interest is "@{[sort @array_1]}" eq "@{[sort @array_2]}".
