Indeed, control of the ordering was not on the table, AFAIU.

If we want to be able to control the order, we will have to completely
redesign how display in the margins works, because currently this is
completely determined by the order we traverse the buffer text during
redisplay, i.e. the 'margin' display property that is on buffer
position displayed more to the left will be displayed before the one
to its right.
