MQX interrupt and task priorities

I'm using MQX on a K70. I'm trying to determine if there is a connection between  the priority of a task as set in the task_template_list, and the priority of an interrupt service routine (as set in the _bsp_int_init  function) used by that task. Table 3-27 in the MQX User's Guide refers to hardware priority and task priority. Where is this "task priority" set? Is the hardware priority referred to in 3-27 the same priority set using the _bsp_int_init function? If I have an isr with a priority of 4, do I have to worry about the priority of the task? The task would be waiting for an event flag to be set by the isr.
