I have to disagree.
If the scrolling text box records damage, so does the ranking system.
ie. "soft gun destroyed" and so on. It tells you this information because you are credited with it's destruction.
You don't get any perks, points & death for damage that happens
after your death, even though the information text will be displayed when you are in tower.
Easy to test it yourself: Drop bombs from alt on a target, bail and exit sortie immediately, while your bombs are still falling. You will get the messages, but no perks or any points for score.
