Actor priority only affects in-memory scheduling not queue order

Actor priority option only takes effect when choosing between messages already consumed from queues and waiting in-memory. It has no effect on message ordering while messages wait in queues, limiting its effectiveness for prioritization.

For effective prioritization, group actors by priority level into separate queues with all actors in each queue having the same priority value. For RabbitMQ, use broker_priority option for queue-level prioritization. Lower numeric values indicate higher priority.
