The sort attribute cannot be dynamically assigned..

What happens is this: DTML is pre-parsed, and all the DTML tags are 
replaced by object instances representing those tags. The attributes are 
stored as instance variables. This means that 'sortby' is evaluated only 
once, when you save the DTML code.

Right now there is no real solution to your problem, other then creating 
different #in tags and selecting one with an if - elseif - else structure.
