I am trying to create a Gadget on a Dashboard that echos out the Epics as they appear in the backlog, i.e. this

follows this

I can create a filter to use in the gadget e.g.
`type = Epic ORDER BY rank asc`
But the order is not the same.
Is there a value that represents the priority order of those Epics that I can order by in my jql?
Or is there another way of having the gadget reflect the order of the Epics in the backlog? Obviously it should track as we drag Epics about to reprioritise.
Many thanks for any pointers.
