Okay, I see why you want to do it. Unfortunately, as far as I can determine, OmniFocus has nothing but an ephemeral notion of the contents and ordering of the context view, unlike the project/planning view. Where something would go in the context view depends on what else is in the view (and the view sort settings), unlike the project view, where the question is merely whether a given action is displayed in the view or not, and how it should be styled, as the order is predetermined. It might be possible for them to support a context view where you could drag items around, but that view wouldn't stick, you wouldn't be able to sync it to your iPhone from your desktop, etc. without substantial engineering effort, I would guess. Certainly, it won't be helping you with tomorrow's trip to the warehouses.

As always, your best bet for seeing a change in the program's behavior is to use the Help->Send Feedback command to get your wishes officially noted in their database.

Here's a workaround you can use given that you seem to have the ability to plan these collection trips in advance:

Go to your Warehouse1 context. Select all of the tasks, and do Edit->Copy. Flip back to Planning mode, make a new project called "Warehouse1 trip". Add a blank action to the new project. Click at the very left end (to the left of the dot) of that action, then paste in all those tasks. If you do this correctly, you'll end up with a project with a blank task followed by all the copied tasks, 1 per task. If you don't click in the right place, you'll end up with 1 task with all of them combined. Delete it and try again. Once you've got it done, you can reorder the tasks to your needs. Repeat for the other warehouses, sync to your iPhone, and use the Project view on the iPhone to track your efforts. When you get back with all the goodies, sync phone and desktop, and you can then do a bulk checking off of the items in the original context views and delete your tracking projects. Does that make sense?
