If you take a look at the script editor, you'll see near the botom of the list Scene_Equip and Scene_Status.
All you need to do in the script command is to call the scenes like that:
$scene = Scene_Status.new
However, both scenes requires arguments to work. They need to know which actor's status to show. So, the script call should look like:
$scene = Scene_Status.new(actor_id)
and
$scene = Scene_Equip.new(actor_id)
Hope it helps!
