I find that if i'm met with a low keyword quality score, i can increase that score by increasing my bid for that specific keyword, or by creating a new ad that will incorporate those keywords in a way adwords identifies as more relevant. It's not that difficult to do. I like to create a new ad and use a few keywords i would like to increase. Of course, you're throwing these new ads into an even rotation in an ad group, so your quality score for that keyword will probably increase based on how many times that ad shows, which bolsters the rankings of those keywords. If you can justify it, create a new ad group and see what happens.
