Why not make it possible for the user to define his/her own scale factors which are not in the default set of available scales?
I guess this is more of an Imperial issue since in metric you can set it to any scale you want.
It would be easy. One would define the text string that would identify the custom scale (E.g.:
1" = 60'-0"). Then he would define what metric scale this is equivalent to (
1:720)
