Valery, I have tested TEW 2, 3 and 4 in ERA 3 and the maps play correctly without scripting errors and something else, the only thing I have to comment on is that the gameplay has possibly been altered so it is required to play the entire maps to see if it's playable from start to finish as it should be. You yourself know how to play your own maps and if you know how the differences are playing with ERA 2.46 and ERA 3.x.x.
