No, this is not allowed.
Priorities in continuous signals are completely static. The value of the
priority is specified by an Integer literal (e.g. 1,2,3). This means that
variables can not be used. The lowest value indicates continuous signal
having the highest priority. A non-deterministic choice is made between
continuous signals with same priority.
I hope this helps.
