Reorder placement rules

Placement rules are evaluated in the order in which they appear in the placement rule list. When a job is submitted, the rules are evaluated, and the first matching rule is used to determine the queue in which the job is run.

If a rule is always satisfied, subsequent rules are not evaluated. By default, placement rules are ordered in the order they were added; the first rule added appears first. You can easily reorder rules.
