ok, i found it but i'm not going to make it custom to fix tikz

you need to use this:

      \normalexpanded{\noexpand\startscope[shift={\p}]}

instead of

       \startscope[shift={\p}]

this can be automated with (maybe we need a m-fixz module for that)

% fix

\appendtoks
     \let\normaltikzstartscope\startscope
     \def\startscope[#1]%
       {\normalexpanded
          {\noexpand\normaltikzstartscope[#1]}}%
\to \everyinsidetikzpicture

% end of fix

but for that you need to use the attached module so that we hook it in 
aftert tikz sets itself up

the fix you can put in your style or in a cont-loc.mkxl in a local tree
