At some semi-states the official scratch list is posted on the scorers table and others note the scratched on the bout card or rotation sheet. However it is generally not to hard to figure out who scratched an official. If Team A and B are wrestling one match and an official is scratched and then in another match Team A and C are wrestling with the same officical scratched most officials would figure out Team A scratched them.
I was scratched by one school at Merrillville. Did I seek out the coach to find out why I was scratched? No. Does it bother me that I was scratched? No. Will I take the scratch out on the coaches or the team at a later date? No. For whatever reason Team A did not want me to work their matches and the scratch was part of the meet time coaching decisions to advance their wrestlers. It is part of the sport.
The important point for officials on being scratched is to not take it personally. As noted above by Chuck, coaches scratch officials for many reasons. Some logical, some not so logical.
