Thank you very much. I was able to get it to work now. I'll paste the custom code I'm using to trigger and display the different icons on top of the items, if anyone is interested.

function(trigger)
    
    if QuestFrameRewardPanel and QuestFrameRewardPanel:IsShown() then        
        
        local index = 1;
        local highestPrice, newPrice = 0;
        
        for i = 1, GetNumQuestChoices() do
            newPrice = select(11, GetItemInfo(GetQuestItemLink('choice', i)))
            if newPrice > highestPrice then
                index = i;
                highestPrice = newPrice;
            end
        end
        
        if index == 1 then    
            return trigger;
        end
    end
end
