There a couple of ways I can think of. The only CommonAdjust documentation 
I could fine dates back to the Minivend days; I adapted it into a document 
called ic_ecommerce some time ago. It's in the IC distribution, and also here:
http://www.insitehosting.com/icdocs/ic_ecommerce.html

You could try the & CODE atom, perhaps something like:

& &tag_data('products', 'price', $Vend::Interpolate::item->{code}) * 
&tag_data('products', 'unit', $Vend::Interpolate::item->{code})

Or you could write a usertag that does a similar calculation to the above, 
call it pack_price, and then invoke it in the CommonAdjust string:

CommonAdjust '[pack_price]'

...Mike H. wrote a pretty good example of just such a usertag; I have 
employed the technique a few times myself:
