IKE posted parts of our scouting system in the CD-media section. At one event this year he and his scouts were 23-24 correct picks (not in order), and the team that wasn't on his list was out in the first round.
For match scouting:
We scouted by "good things". These include passes and scores, equally. This values a mid or far-zone bot as much as a front-zone striker, so the ones who steal the balls and pass get as much credit as those who finish the job. We had a sheet for each team, and scouted six matches per team. One sheet was dedicated to them, with six squares for data. On the back, the scouts would write comments on their performance and opinions of the teams. We also noted if they hung.
For pit scouting:
I don't know as much about this. We had a pit scout who took notes in a notebook.
For pick list time:
On Friday night, six mentors would go to dinner with the scouting data and make the pick list. In Atlanta, we had the discussion in the hotel and involved more mentors and students, talking about each team that was decent, picking our favorite first and second picks, etc.
