Adding a couple cents.
I would say that the order matters, and in the SDP it should correspond to the order of the `encodings` in `setParameters` on the transceiver.
However, i do not think that the actual contents of the layers should be restricted to having any particular order.
it should be fine to define _hi,med,lo_ or _lo,med,hi_ or even a jumbled _hi,lo,med_. This would be based on your preference for congestion control etc. as suggested in the comments above.
Signaling the interpretation of each layer can be done using the rid restrictions (ex. `max-width` and `max-height`).
