Improvement in current issue boards for scrum methods

Problem to solve

Currently issue boards do have a way to prioritize issues on order as described in #21264 (closed). But this system should get some improvements to allow a better scrum/agile work method.

Further details

We are using a issue board as a scrum board for the current sprint. Which means we need all issues in the OPEN column ordered with the most added value on top and least added value at the bottom.

After the OPEN column we have columns like doing, waiting for approval, approval in progress, etc. and at last we have the CLOSED.

Some issues with ordering in these boards arise or could be improved, being:

We can only change the ordering in the OPEN column by moving issues from the bottom to the top. When we try to put an issue from the top to the bottom it won't save this order. This seems like a ~bug to me for issue #21264 (closed).
When issues are moved from OPEN to the 2nd lane and from the 2nd lane to the third lane it would be nice to keep the order in place. Meaning the one with the top priority in OPEN will be the top one in 2nd lane etc.
Even if issues are in the CLOSED and are reopened during the sprint. It should be priority number 1 in the OPEN
It also looks like everyone (maintainers, developers, reporters) can all re-order the priority in the boards. I think this should be a maintainer feature at least.
