A particular receiver can only process one broadcast at a time. As each broadcast happens, it is processed to determine the targets it should go to, and dispatched into the message queue for each target. When a later broadcast is sent, it will generally not be moved ahead of the queue.
For the screen on/off broadcasts, you can rely on the most recent broadcast you get being the current state of the screen. once everything has settled down. You can't rely on ordering with any other broadcasts, or other broadcast receivers that may also be receiving the broadcasts.
