We also know of implementations, both on the sender and on the receiver 
side (as far as I remember) that use ordering. So maybe something like:

"If no quality values are assigned or multiple language tags have been
assigned the same quality, the same-weighted languages may be listed in
descending order of priority."

I'm sure somebody can come up with better wording, but I hope you get 
the idea.

Regards,   Martin.
