taxonomy weight filter

I don't know is it realy bug, but term's weight is integer, so I think that filter handler must be views_handler_filter_numeric:

  // taxonomy weight
  $data['taxonomy_term_data']['weight'] = array(
    'title' => t('Weight'),
    'help' => t('The term weight field'),
    'field' => array(
      'handler' => 'views_handler_field',
      'click sortable' => TRUE,
    ),
    'sort' => array(
      'handler' => 'views_handler_sort',
    ),
    'filter' => array(
      'handler' => 'views_handler_filter_string', // views/modules/taxonomy.views.inc line 199
    ),
  );

      'handler' => 'views_handler_filter_numeric', // views/modules/taxonomy.views.inc line 199
