I've owned several, and seen hundreds. Again, the only time rods were marked for different tapers was when lines were rated by diameter (letters) and a level line of a given letter weighed more than a DT line with the same middle letter. Once lines started being rated by weight (numbers) taper went out of the equation. A rod marked with several numbers means only that the rod can be reasonably expected to cast lines of those weights. The taper of the line has nothing to do with it.Do you have a rod marked like that? I'd ask the rod maker what they have in mind with those ratings.
