The game acknowledges your actions with accolade cards. There are both good (like extracting bounty) and bad ones (like you getting killed).
Accolade cards have an internal ranking that gives them more value, the better the achievement. So, killing two hunters is less impressive than killing 8 hunters. This quality-grading is represented by the the trimming of the card and also yields a higher amount of Blood Bonds.
The Top list, takes the highest quality accolade cards and highlights them separate from the rest. Only the top-5 cards can yield Blood Bonds.
Additional accolade cards that award extra cash or bounty are listed under "other".
In case there have been less than 5 valuable cards, it won't be a Top 5, but a Top 4, 3, etc.
Hope this helps!
