It is now as simple as verifying whether the values of any of the columns in the sort order (#onreadinglist ... etc) changes when you remove a book from the reading list.
I do not know your setup and you did not mention the '#readorder' before and whether it is updated by the reading list plugin. As I said before, without having the full data I'm just shooting in the dark, and will not reach anything. My hunch is that the books are moving to bottom to honor the current sort order.
