You have no ordering guarantees, so how can order be important? If 4 work items are scheduled on 4 independent workers, you have no guarantee which will start first or finish first.

The order matters in the sense that the 5th jobs should not be atempted before those 4.

I think the order matter at least because you want to have some FIFO approximation, otherwise some tasks can forever stuck in queue and never be picked up.

Then I think what you actually care about is scheduling fairness, and a strict ordering of execution of job 5 after job 4 is unimportant.
