Thanks for Wolfgang: your solution, that is \setuprandomize[2012] \define[3]\RandomCoeff{% \setvalue{Coeff#1}{\ctxlua{tex.print(math.random(#2,#3))}}} works indeed and it is somehow simpler than using \expandafter\csname, and as a matter of fact, after reading your message I searched in the ConTeXt manuals written by Hans, and found that \setvalue is defined on page 93 of module-01.pdf as \def\setvalue#1{\expandafter \def\csname#1\endcsname} so it is better to use it.
