The following should handle both those cases:

Lua Code:

local CustomAuraFilter = function(icons, unit, icon, name, rank, texture, count, dtype, duration, timeLeft, caster)
       local isPlayer
 
       if(caster == 'player' or caster == 'vehicle') then
               isPlayer = true
       end
 
       if((icons.onlyShowPlayer and isPlayer) or (not icons.onlyShowPlayer and name)) then
               icon.isPlayer = isPlayer
               icon.owner = caster
 
               -- We set it to math.huge, because it lasts until cancelled.
               if(timeLeft == 0) then
                       icon.timeLeft = math.huge
               else
                       icon.timeLeft = timeLeft
               end
 
               return true
       end
end
 
local sort = function(a, b)
       return (a.timeLeft and a.timeLeft) > (b.timeLeft and b.timeLeft)
end
local PreAuraSetPosition = function(self, auras, max)
       -- Make all hidden icons "invalid"
       for i=1, max do
               local icon = auras[i]
               if(not icon:IsShown()) then
                       icon.timeLeft = nil
               end
       end
 
       table.sort(auras, sort)
end

CustomAuraFilter is pretty much a copy/paste of the one oUF uses internally, but with timeLeft added.

Error on line 24, comparing number with nil.
