Marty Kraimer answered this question. Turns out the 
sequencer will not honor  a priority parameter value 
of less than 100.

The relevant code from seq_main.c is:

        /* Specify task priority */
        pSP->taskPriority = SPAWN_PRIORITY;
        pValue = seqMacValGet(pSP->pMacros, "priority");
        if (pValue != NULL && strlen(pValue) > 0)
        {
                sscanf(pValue, "%ld", &(pSP->taskPriority));
        }
        if (pSP->taskPriority < SPAWN_PRIORITY)
                pSP->taskPriority = SPAWN_PRIORITY;
        if (pSP->taskPriority > 255)
                pSP->taskPriority = 255;

        tid = taskSpawn(ptask_name, pSP->taskPriority, SPAWN_OPTIONS,
         stack_size, (FUNCPTR)sequencer, (int)pSP, stack_size,
(int)ptask_name,
         0,0,0,0,0,0,0);

where
seq.h:#define SPAWN_PRIORITY            100

:(
