Description of problem:
When sorting by score in System Currency systems are not sorted correctly. 

Version-Release number of selected component (if applicable):
1.5.56-1.el5

How reproducible:
Reproducable very time

Steps to Reproduce:
1. Click Systems -> Systems -> System Currency
2. Sort by score
  
Actual results:
Systems with the highest score is not listed at the top of the list as they should. 

Expected results:
System with the hightest score at the top of the list. 

Additional info:
It looks like this is a java-script bug: 
javascript:sortColumn('list_1646781657_sortby_id', 'created', 'list_1646781657_sortdir_id', 'desc')
Should probably be score or similar, instead of created.
