That is not how queues work. A queue is a FIFO structure. This is the lamest excuse I have heard yet for why my 10k withdrawal hasn't been processed in over 9 weeks.
In Computer Science we often use more efficient or fair
queue diciplines than FIFO. FIFO is not a perfect dicipline if the object is to give as many customers as possible acceptable service, and very unfair if they are limited to a number of transactions/day. In that case anyone can stall the queue, causing Denial of Service to other customers, by making many small withdrawals instead of one large.
You have had a 10k EUR SEPA withdrawal in queue for over 9 weeks? I just did a 7k withdrawal. It will be interesting to see how long it takes. I never withdrew fiat from MtGox before.
