You are right.
My test here was too quick, but the two-liner worked for me, because the 
point I had chosen for the test was inside an image whose script 
contained "put the mousecolor", as I now found out.

For your solution I would recommend to add "globalloc()" to easier 
access points on the card, like

   "put 545,410 into tloc
   lock screen
   put the screenmouseLoc into coord
   set the screenmouseLoc to globalloc(tloc)
   put the mousecolor
   set the screenmouseLoc to coord
   unlock screen"
