It could have been that you used \def which doesn't work because this
will always
call the Lua function and you get a new random value but with \edef the
result
of the first random value is stored in the macro.
\def\RandomA{\cldcontext{math.random(1,4)}}
\edef\RandomB{\cldcontext{math.random(1,4)}}
\starttext
\dorecurse{10}{A: \RandomA \quad B: \RandomB\par}
\stoptext
