There is no automated sort with OneNote to do this. You will need to
manually move them into the desired order by right-clicking on the
folder/section tab and selecting "Move". In the dialog box that follows,
select the location to move the object into. If you are looking to manually
sort, you will be moving into the same area where it was before, but the
object will be placed at the beginning of the list. It's not too intuitive
at first, but once you get the hang of it, it's pretty straightforward.
And, please take this as the friendly advice that is intended: don't post in
all capital letters. It is difficult on the eyes and is considered the same
thing as shouting in the real world.
