scores of other unsought inducements

[tesoke]

Hi, I cannot understand the meaning of the red part of the following sentence from “I’m a stranger here myself” by Bill Bryson. Would you please explain it to me? Thanks a lot.

There among the usual copious invitations to acquire new credit cards, ..., and the scores of other unsought inducements, and ... .

Score = a group of 20 (compare, dozen = a group of 12)
unsought = unrequested; that had not been requested; that were not wanted, etc.
