I think the FAI rules would have handled this situation just fine.
You would have been scores as landing out at the class C boundary and
the distance on that leg would have been scored as progress toward the
second turnpoint.

How does the scorer know where to score to if someone aborts
normally? *Doesn't the scoring program look for the farthest logger
point in the direction of the next turnpoint (that isn't actually
reached) to determine how to score distance, after it determines that
the task wasn't completed? *Then it would seem easy to not assess a
violation for any airspace incursion after that point is determined.
The scorer shouldn't have to do anything.

But I admit I'm assuming a lot about Winscore, so may very well be
completely wrong about this.

I can definitely lay out some tasks in relation to restricted areas
(like Class C's) where the pilot would be required to backtrack away
from the next turnpoint (and home) to avoid the -100 point outcome if
s/he abandoned the task and elected to traverse the restricted area.
This would require careful piloting to ensure that your greatest
progress towards the next turnpoint was outside the restricted area.
To make this really obvious imagine that the second to last turn is
across a Class C from home and the last turn is a steering turn just
20 miles abeam of the finish. *You'd have to do some clever
trigonometry to figure out how to cross the Class C after making the
second to last turn in order to get home without making progress
towards the final turn within the restricted area.

But this answer displays some of the wisdom of current policy. We
don't allow flight in or over class C because it would give a
competitive advantage to those having a transponder. Originally, it
seemed like "but the race is over, so there's no competitive
advantage" was a good argument. But in this and a previous example,
it's clear that being able to press on while keeping the option alive
to glide home over the class C is a definite competitive advantage.

Bottom line, though: Given the amount of complaining from many people
about complex rules, carving out an airspace exception to fly over
class C as "self retrieve" doesn't seem like a good idea.

For a non-sanctioned contest, make up your own rules and do whatever
you want.

If a sanctioned contest really wants to do this, they should apply for
a rules waiver. It might make sense at El Tiro given the very odd
geometry of the Tucson class C relative to El Tiro and the soaring
area. That lets you adapt rules to local conditions without us having
to write some nightmare into the rules that apply to everyone.
