Our (that is, German syntax) rules state that text mode numbers should ouly
be written out as number words up to twelve. But there are text mode
numbers which are definitely not maths, as in

        ``in the summer of '69''
        ``they were not only pirates, they were The Wild 13''
        (The number of the beast is $666$? I don't think so.)

Also, I tend to treat enumeration numbers (\thesection, \itemize-items)
as text number's, raising them to the third makes to sense.
