Looking at the rule book.
111e/4
We had an individual/team pre-bowl because they had to work. Later they found out that they would not have to work on that date so they appeared at the lanes to bowl.
Can the league secretary throw out their scores and allow them to bowl?
No. When an individual or team receives permission from the league and completes their prebowl, they have exhausted their eligibility for that league session.
111e/5
The league had a team pre-bowl for a specific league session. The team pre-bowled
and then, due to severe weather, the league cancelled bowling on that date and
resumed the following week. What happens to the pre-bowled scores?
If the team pre-bowled and the league session was subsequently cancelled, USBC
recommends the board meet and choose one of the following options:
Option 1: The pre-bowled scores are applied to the rescheduled league session. The team would not be permitted to rebowl that week as their scores have already been recorded and their eligibility exhausted.
Option 2: The league board null and voids the pre-bowled scores and the team is allowed to bowl the rescheduled league session.
