this should help:

\unexpanded\def\writeviatex#1#2%
{\ifx\normalwrite\relax\else
  % the \detokenize makes sure we don't expand \noexpanded macros
   \normalwrite#1{\detokenize{#2}}%

in what sense wrong?

Content of the external file from MkIV (the entries on the first page show 0
and the values on page 2 and 3 are always the same):

1:0:0
2:0:0
3:4661756:45255023
4:4661756:45255023
5:4661756:45255023
6:4661756:45255023

Content of the external file from MkII (different values for the first
and second position on each page):

1:6526435:46204089
2:4661756:45256000
3:6526435:46204089
