Perhaps it would be worth coming up with something new, but we already have the "Grails" system, which VDV worked on so hard. Let's try using it ourselves?
After all, we already have online rankings (with several reports per day), and this is done without an integrated program in the forum. I see it this way: a regularly updated HTML table, and we can require all organizers of official tournaments to post in the topic with this table or in another topic with links to the tournament results, based on which Grails will be awarded.
There will be one person responsible for maintaining the Grails table; I think we have many enthusiastic people who can take on this task. If possible, we can later write a program that will make it easier for this responsible person to fill out and update the table (as Starhan did for maintaining the online ranking for Heroes of Might and Magic V).
As many already understand, if we don't do this ourselves, no one else will do it for us.
