Interestingly, this week I was starting a new campaign for a client with a bunch of brand new keywords, and they all went in at QS10 as well. This account is in great shape; very few keywords under QS7 and in fact last time I added a bunch of new ones, they defaulted to QS7. But this time it was 10. A few hours later, they were all 7's. Just figured it was some Google weird.
