With %S RefTeX figures out which section _level_ the label will be put in
and inserts the respective string defined in `reftex-section-prefixes'.
In contrast, you seem to want to obtain the numbering as in the typeset
document.  I am not aware of a built-in method to do this.

Getting the numbers as in the typeset document will be very hard.  You
would probably have to parse output files.

In any case, RefTeX works with label types which are related to the
label prefix.  If the prefix becomes subject to change, determination of
the type during referencing might become problematic.
