The priority is mapped only when it is defined in the AADL model.
So, if you specify the priority in the thread component, it should be
ok. Then, the thread component would look like this :

thread mythread
.....
properties
	Priority => 5;
end mythread;

thread implementation mythread.i
....
end mythread.i;

Then, the generated code will look like this:
  RETURN_CODE_TYPE ret;
  tattr.ENTRY_POINT = thr1_job;
  tattr.BASE_PRIORITY = 5;
  tattr.DEADLINE = 500;
  tattr.PERIOD = 1000;
  tattr.STACK_SIZE = 4000;
  tattr.TIME_CAPACITY = 1;
  CREATE_PROCESS (&(tattr), &(arinc_threads[1]), &(ret));

Hope that helps :-)
