So far I think I was able to work around using function...

  #declare choose_texture = function(x,y,z) {
    (
    ((y>=abs(x))&(y>=abs(z)))*1+
    ((x>=abs(y))&(x>=abs(z)))*2+
    ((z>=abs(x))&(z>=abs(y)))*3+

    ((-y>=abs(x))&(-y>=abs(z)))*4+
    ((-x>=abs(y))&(-x>=abs(z)))*5+
    ((-z>=abs(x))&(-z>=abs(y)))*6
    )/6
  }
