Use the 'insertBefore' method of the dom::node command.
Ie. get the token of the child you want to move, the token
of the node you want to move the node in front of, and the
token of the parent.  Then:

   dom::node insertBefore $parent $moving $inFrontOfMe

This method automatically updates the tree to make the move
happen.  It works no matter where in the tree $moving was
originally.
