Allow other modules to also preprocess JavaScript

My module needs to also preprocess the JS attributes and run AFTER jQuery Update, but when it does it wipes out jQuery Update's replacements. I have added this ONE line code in the jquery_update.module, line 83:

function jquery_update_preprocess_page(&$variables) {
-------- CODE -----------
+     $variables['js'] = $scripts;
       $variables['scripts'] = drupal_get_js('header', $scripts);
    }
  }
}

By assigning: $variables['js'] = $scripts; This allows me to use the JS array you modified. For those who do not have jQuery Update installed, I use this code to load the Drupal's JS array if $variables['js'] doesn't exist.

  if (!isset($variables['js'])) {
    $variables['js'] = drupal_add_js();
  }
  $javascript = $variables['js'];
