How to reorder items pulled from separate inventory locations?

When items are "picked" for orders from the inventory racks, their order is mixed up due to conveyor pathing. The bottom right conveyor loop needs to be set up to reorder the orders pulled via broadcast from the customer who receives the shipment. Once the order is re-ordered it is stored in the rest of the right-side conveyors (front to back) until the last order is stored.

In the ProcessFlow, the three Scheduled Sources create tokens that match with the three different types of product in the inventory rack as a "Pick List/Purchase Order". They currently create on an exponential basis for troubleshooting rather than through use of an external source (like a broadcast), as this is one of the things I am struggling with implementing.

Any help would greatly appreciated. I've attached the model.

I don't think we have enough information for this. There are no references to the (purchase?) order in the model to which the picks belong. What do the 3 type represent - just 3 types of product? Please explain it a bit more.

I've updated the question in the second paragraph to hopefully clear up your questions. Let me know if I need to try to explain it better. Thanks.

@Sean B, @jason.lightfoot,

Is this question sorted? Should we accept Jason's answer? Since this is a public question, is there a solution to describe?

The model I posted just has a simple loop where items are allowed to exit when they are the head of the loop and match the next sequence number. In reality the items are held at the correct positions in the sequence with gaps for other items to be inserted. When an item is released as the next sequenced item, all held items should index forward. @Sean B if you still want help with that let us know how far you got.
