Alter node menu local task weight of "View" and "Edit" for a content type

Question

I want to alter the ordering of the node tabs for a particular content type.

• From this: View, Edit
• To this: Edit, View

I tried with using menu_local_tasks_alter like this:

function wedding_registry_menu_local_tasks_alter(&$data, $router_item, $root_path) {
      foreach ($router_item['page_arguments'] as $key => $argument) {
        if (is_object($argument) && $router_item['page_arguments'][$key]->type == 'my_wedding_registry') {
            dpm($data);
            foreach ($data['tabs'][0]['output'] as $key => $link) {
                if ($link['#link']['path'] == 'node/%/view') {
                    dpm($link['#link']['weight']);
                    $data['tabs'][0]['output'][$key]['#link']['weight'] = 5;
                    dpm($data['tabs'][0]['output'][$key]['#link']['weight']);
                }
                elseif ($link['#link']['path'] == 'node/%/edit') {
                    dpm($link['#link']['weight']);
                    $data['tabs'][0]['output'][$key]['#link']['weight'] = 4;
                    dpm($data['tabs'][0]['output'][$key]['#link']['weight']);
                }
            }
            dpm($data);
        }
      }
    }

Devel is showing the $data array correctly modified:

• first with the default weights (View = -100, Edit = -99)
• after with my modified weigths (View = 5, Edit = 4)

but the tabs on the page are still on the same positions even after clearing the cache!
