Random permutations of radio button answers in Stack

Hello everyone.

I've added two radio button inputs into my Stack question, and I've defined them as follows:

ta12: mol*dm^-3,true],[mol,false],[mol*kg^-2,false],[mol*g^-1,false;

random_permutation(ta12);

unit1: g*mol^-1

ta13: 160*unit1,true],[100*unit1,false],[420*unit1,false],[100*mol*kg^-2,false;

random_permutation(ta13);

My problem is that the random_permutation(ta12 or ta13) command doesn't do anything, the answer options always remain in the same order. What could be the solution? Thank you. (Other details are belowsorridente

Both inputs, for ta12 and ta13, are set to radio; model answers are ta12; and ta13 respectively; 

PRT for ta12: the answer test is set to AlgEquiv, SAns: ans12, TAns: mol*dm^-3, test options: 0;

PRT for ta12: UnitsAbsolute, SAns: ans12, TAns: 160*unit1, test options: 0.
