Then maybe you could use one tag for each of those grades:
     climbing:grade:aided                     = A3
     climbing:grade: yds_class              = 5.9/A3
     climbing:grade:yds_class[max]    = 5.13

...or something like that.
You might even add a converted grade (although the conversion isn't 
unique since 5.13 might be anything between 7c+ and 8b):
     climbing:grade:french                    = 5c/A3
     climbing:grade:french[max]         = 8a+
