There are 2 different issues involved here: the sorting mechanics and 
the sorting theory.

Sorting Mechanics
============
The mechanics are simple.  A linear ordered sequence of symbols can be 
assigned to any sign.  The symbols automatically sort according to the 
ISWA 2010 default order using a binary string comparison.  In our 
programs we can use > greater than or < less than comparisons.  From a 
database, we can use a simple "order by" clause.

For each symbol, there are 2 kinds of mechanical sorting.  The major 
sorting between symbols and the minor sorting within symbol bases.

For the major sorting between symbols, the list below is sorted by the 
default ISWA 2010 order.  Order other than this are possible, but 
require an additional step of creating a custom ordering of the 
symbols.  Only the default ISWA 2010 order has been implemented. Unicode 
has a way to reorder the major sorting issues involving special weights 
for each symbol base.



For the minor sorting within the symbols, the default order starts with 
Fill 1 and Rotation 1.  Next is Fill 1 with Rotation 2, then the rest of 
the rotations for Fill 1.  After that are the symbols with Fill 2.  Only 
the default ISWA 2010 order has been implemented.  This may be an issue 
when the default ISWA 2010 order is not the desired order.  Unicode may 
possibly have a way to reorder the minor sorting, but I'm not sure.




Sorting Theory
=========
For sorting, the linear ordered list of symbols can be created using any 
writing symbols and any detailed location symbols.

Creating the special sorting requires crafting a special sequence.

If I understood Charles correctly, he would want to use Head Rims.



Head Rims have a default sort order of the following...


So the first symbol in the ordered sequence would be the dominant hand 
shape.  The next would be the appropriate Head Rim.  The third symbol 
would be the non-dominant hand.

Regards,
-Steve
