The 10mm cartridge has only been around since 1983, and Winchester didn't introduce the Black Talon ammunition line until 1991 (discontinued in 1993), so no, the 67 stamped inside the box doesn't refer to the year of manufacture (most likely part of the batch number).
Best guess, based on the price marked on the primer package, is that it's from the early 90s, too.
Edit: Found a post on another forum wondering about the age of an identical package of primers, where a forum member indicated late 80s to early 90s vintage.
