Cones are created pointing upwards along the positive Y axis. PointEntity points the entity along the positive Z axis. You will need to use RotateMesh to rotate the cone 90 degrees on the X axis for it to be pointing in the correct direction.

eg. RotateMesh cone, 90.0, 0.0, 0.0

As I understand it, the roll parameter of PointEntity just rotates the source entity on its local Z axis, which is probably not something you are going to need.
