If they used reggie (the software program) to run the competition, then your score sheets may have been scanned and are available to see on the program website. When you registered, did you use reggie?
What was the name of the competition?
Also, sometimes if you say you're a member of a homebrew club, they give the medals and score sheets to a member of that club to take back to the next meeting.
Other than that, I am not sure what you should do.
