Currently, the alarm list is sorted alphabetically by alarm title, but you can still see the activation order for the next 10 alarms by looking at the "Upcoming activations" section of the alarm log (which you can make visible by clicking the link at the bottom right-hand corner of the alarm list window.)
I may include an option to sort the alarm list itself by each alarm's next activation date, but I expect that could be problematic for some people, as the order of the list would change depending on the time and day you look at it.
