This is by design. The $WCMIXED?x:y$ expression does not support other
replacement statements as the x:y params. Because it is not fixed in
which order the expressions are evaluated/replaced in the file.

That means, you can not nest expressions.

You have to work around that using e.g. defines:
#define RANGE $WCRANGE$
#define REV $WCREV$
#define SVN_REVISION "$WCMIXED?RANGE:REV$"
