iTween.RotateAdd Gives Wrong Results

I'm trying to create an obstacle course where the player has to pass through rings with the top of their avatar oriented at a certain angle, indicated by a pointer on the ring. Comparing the player's eulerAngle.z with the ring's works as long as the player enters perpendicular to the ring, but breaks down if the player enters at too much of an angle.

So, I think, I'll make an invisible game object, rotate it so it faces the ring correctly, and then measure its eulerAngle.z. Code as follows:

    `marker = Instantiate(emptyObject, col.gameObject.transform.position, col.gameObject.transform.rotation) as GameObject;
 float rot_needed_x;
 float rot_needed_y;
 
 if(marker.transform.localEulerAngles.x < 180f){
    rot_needed_x = marker.transform.localEulerAngles.x / -1;
 } else {
    rot_needed_x = 360f - marker.transform.localEulerAngles.x;
 }
 
 if (marker.transform.localEulerAngles.y - 90f > 90f - marker.transform.localEulerAngles.y){
    rot_needed_y = (marker.transform.localEulerAngles.y - 90f) / -1;
 } else {
    rot_needed_y = 90f - marker.transform.localEulerAngles.y;
 }
 
 Hashtable rotHash = new Hashtable();
 
 rotHash.Add ("x", rot_needed_x);
 rotHash.Add ("y", rot_needed_y);
 rotHash.Add ("z", 0);
 rotHash.Add ("time", 0.1f);
 rotHash.Add ("oncomplete", "GetFinalScore");
 rotHash.Add ("oncompletetarget", this.gameObject);
 rotHash.Add ("easetype", iTween.EaseType.linear);
 rotHash.Add ("looptype", iTween.LoopType.none);
             //Now rotate marker and output new Euler angles
 
 iTween.RotateAdd(marker, rotHash);`

What's killing me is this: the code correctly figures the needed rotations, but after they're applied the end Euler angles (checked by the GetFinalScore function called when the animation completes) don't match the ones I want. So for instance, I get the following output using some print statements:
