URI has an eq function/method but it doesn't consider ...?joe=1&jack=2 and ...?jack=2&joe=1 to be equivalent. 
use strict;
use warnings;

use URI ();

my $base_uri = 'http://host/index.html';

my $uri1 = '/bob?joe=1&jack=2';
my $uri2 = 'http://host/bob?jack=2&joe=1';

$uri1 = URI->new($uri1)->abs($base_uri);
$uri2 = URI->new($uri2)->abs($base_uri);

print($uri1->canonical, "\n");
print($uri2->canonical, "\n");

print(URI::eq($uri1, $uri2) ? "equal" : "not equal", "\n");

Output:

http://host/bob?joe=1&jack=2
http://host/bob?jack=2&joe=1
not equal
