This is a mixture of a bug and feature. I'm not sure if the following patch 
is completely safe (so i'll have to test it for a while)

\unprotect

\def\preparethenumber#1#2#3% {\??id#1} \number \result
   {\doifelsevaluenothing{#1\c!scheider}
      {\let\numberseparator\empty
       \let#3#2}
      {\edef\numberseparator{\getvalue{#1\c!scheider}}%
       \edef#3{\@EA\separatednumber\@EA{#2}}}}  % hm, etex

\protect

the best way to handle sep's is

\definesymbol[MySep][--]

separator={\symbol[MySep]}
