RezObject Weirdness

When an object is rezzed it seems to be rezzed in a weird position. The object is lying flat on it's back and not upright as I had originally created it.

Is there a way to rez the object upright?

I think it's rezzed in the odd position becuase of the "Zero_vector" and "zero_rotation" portion of code:
llRezObject("Coin", llGetPos() + < 0, 0, 0.3 >, ZERO_VECTOR, ZERO_ROTATION, 42);

Am I right? If so, how do I eliminate it without damaging the script?

Rez a copy manually. Rotate it so that it is oriented like you want it when it is rezzed. Drop this script into the root prim:

default
{
   state_entry()
   {
      llOwnerSay((string)llGetRot());
   }
}

Then replace ZERO_ROTATION in your rezzer script with the output you get. (You can then delete the above script from the object you put it in if you like.)
