Sorting saved queries in ADUC console
Solution 1:
Built into the ADUC:
You can create multiple folders to help categorize them, such as "User Queries", "Computer Queries", "Used by Helpdesk", etc.
Other than that you are limited to sorting by name or description, so you can alphabetize them based on name.
EDIT: It appears that if you create a temp folder and then move the queries in there it will auto-sort alphabetically at that point. So create your various folders to categorize or just create one called "Temp", move them all in there, and then move them all back under "Saved Queries".
