I generated polygons using fishnet in ArcMap, since the polygons didn't fall exactly on top of my raster image, I had to edit and move some of them. Now the FID of my polygons are all messed up, and are not in the order that I want them to be (I want them to start from top right and end at the bottom left).
You can try the Sort Tool. It can be used to sort by attribute, or more importantly for you, spatially. It allows you to pick which corner (i.e. upper right) to give priority when sorting.
