There is no perfect way of doing this with Orage as it starts counting 
on Start date
and you are actually interested about due date.
I would do it like you said and create TODO starting on 20th and giving 
10 days time
(duration 10 days). On March and December it would then look like 
delayed even though
there is still 1 day time (as due day is 30th).

Other way would be to create 4 separate TODOs, but that is hardly any 
better.

Another ugly way would be to (mis)use EVENT and set each done date as an 
Exception, which
removes that EVENT from the calendar and can be used as "Completed" mark.

No perfect solutions, sorry.
