When using Vertical Tabs and CCK Groups Feeds is the first tab and can not be moved.

There is no way to move the Feeds field in the Fields list. Will you add this to the fields list or add a #wight setting to the form?

      $form['feeds'] = array(
        '#type' => 'fieldset',
        '#title' => t('Feed'),
        '#tree' => TRUE,
      );

      $form['feeds'] = array(
        '#type' => 'fieldset',
        '#title' => t('Feed'),
        '#tree' => TRUE,
        '#weight' => 100,
      );
