First I think you should create the new levels first in your active file 
 then later (I snipped this out from the microstation help under levels keyins, lots of good stuff there worth printing for future use) 
 you can use the level element move, to move all objects from one level to another level

LEVEL ELEMENT MOVE [dest:level-spec2] <level-spec1>

Moves all elements on &ldquo;level-spec1&rdquo; to specified destination &ldquo;level-spec2&rdquo;. The destination level specification is optional. If it is not specified, then the elements are moved to the &ldquo;Default&rdquo; level.

Then use the keyin to delete empty levels or the compress command with all the options preset 
 I suggest you break your script up and test it then join back up if it all works... 
 if you save your script say c:	emp\script.txt 
 you can add it to an F key as @c:	emp\script.txt then you can run it on a single file by pressing the assigned F key instead of batch processor this is also a quick way to test the script so you dont damage a lot of files with trial and error or just want to do it to one file, plus its quicker than typing @c:	emp\script.txt ...
