What can a user expect from reporting metadata errors?

See for example Dvorák: Symphony no. 9: Unexpected/wrong lyrics - #12 by BlackJack where I had to choose the 1985 edition over the default (for me) 1993 edition that I own.

@joel What is the sort order for the different editions, or actually what determines the default? Release date (newest first), popularity, best match, the most distinctive edition (most types of entries and therefor with the highest chance of errors), something else?
