Lionel:
What is suppose to happen is the rules should fire in this order:
Assign task rule
Audit Task Rule
Route Task Rule
Suspend Task Rule
I've re-numbered the rules to show this sequence.

If that last rule you defined is activated it will fire first and set the
status to "suspend", so no other rule is fired.
If not you will likely have the rules firing in the following sequence
RouteTask, AssignTask, AuditTask, AssignTask, AuditTask, AssignTask,
AuditTask... forever.
Or have I missed the ending condition.
