One way to achieve this, possibly, is to use the little-known feature of the 
AttributeIndex which can use multiple attributes to sort. Say the first 
attribute is the section name, the second attribute would then be used to sort 
the section and that one could be ascending or descending. Dynamically 
changing the second attribute's sorting could be costly though unless the 
section isn't too large.

What is a 'Calculated' method ?

If this order is modeled by a ref collection (or a numeric index), the order 
is persisted and can be arbitrary, ie, user chosen.
