The number of dots is not limited, at least not reasonable. :(
Also the user might alter the field (IOW append dot letter sections or change the whole thing). Thats why I like to have it as index expression - it would sort itself.

>create 3 virtual columns with the dot as separator, order columns on padl(evl(int(val()), 999),3). Then think about the last Item, AA ;-)
