I have not done this, but I understand that many teams which use electronic scouting rely on cell phone internet. Unless you were going to spend a bunch of money on devices and service, this would require that you have enough people on the team with tablet phones or at least rather large big cell phones.

If all of your scouts will be in the same area (say, one row of seats or bleachers), you could set up a wired network among them. (Bring an UPS to power the router?) It would probably be easiest to have each scout populate a different spreadsheet for each match, and spend a minute or two merging them into the master spreadsheet afterwards, a full worksheet at a time. Just name the tabs differently for each match/scout combination, but consistently, and it should be easy.
