You could sort the Worker Quick Incidents List but it will be temporary only as any upgrade, hotfix will overwrite the change. You will need to do it again on the new version, hotfixes, upgrades, repair, etc...
**** MAKE A BACKUP OF YOUR ALTIRIS_INCIDENTS DATABASE ***
You need to change the queries:
They are in the table Query in the database Altiris_incidents.
SELECT * FROM quick_incident
SELECT * FROM quick_incident ORDER BY quick_incident_name
And change QuickIncidentList
SELECT * FROM quick_incident where quick_incident_status = 'a'
SELECT * FROM quick_incident where quick_incident_status = 'a' ORDER BY quick_incident_name
