When using RSO mod and AAI vehicles together, scanning tiles that contain ore returns a signal that includes the ore in that tile (as intended). Using an arithmetic or decider combinator to isolate the ore in the signal does not work, as the selectable ore signals are not the same as the ore signal returned from tile scanners. When hovering over iron ore generated by RSO mod, the tile metadata shows "Base mod > Resource Sawner Overhaul > Alien Biomes", but the iron ore signal's metadata shows "Base mod > Krastorio 2". This may or may not be fixable from Krastorio 2's end, but I wanted to report the issue anyways.
