The text on earing a tag badge from the badges page states:
You must have a total score of 1000 in at least 200 non-community wiki answers to achieve this badge.
That is the correct requirement for a gold badge in any tag.
But when you click on the badge itself, it'll show the badges awarded in a specific badge:
Earned at least 1000 total score for at least 80 answers in the minecraft tag
Bold emphasis, mine.
