    drupal_get_schema(FALSE);
    db_lock_table('themekey_properties');

    // new entry should be added at the end of the chain
    $weight = db_result(db_query("SELECT MAX(weight) FROM {themekey_properties}"));

    // if query fails $weight will be FALSE which will cause $item['weight'] to be set to '1'
    $item['weight'] = 1 + $weight;
    drupal_write_record('themekey_properties', $item, array());
