FirstsortedValue returns null (show both results)

[jgreen95]

I am using the firstsortedvalue  to list regional performance by rank. Occasional regions have the same number of failures, is there a way to include a second priority sorting factor (e.g. alphabetical) as i want to list both regions when they have the same value and i don't mind which way round.

Current formula i am using: 

FirstSortedValue(Region, -Aggr((COUNT(DISTINCT{<[Inspection Outome]={"Failed (Higher Risk/Dangerous)"},
[Inspection Logged-Notification Created Date.MyCalendar1.WeekEnd] = {">$(=[Current Week])"}>} INSPECTION_NOTICE_ID )), Region),6)
