Welcome to the Q&A Forum

This article might be able to help a little.  It does not use SEO Moz campaigns to track keyword performance but does discuss how you can crawl search results from google for a to group keywords and then pair those results with data from Open Site Explorer.  You would not necessarily be interested in the second part.  Perhaps the spreadsheets discussed in these articles can help? http://www.seomoz.org/ugc/competitive-analysis-in-under-60-seconds-using-google-docs-12649 http://www.distilled.net/blog/seo/how-to-build-agile-seo-tools-using-google-docs/ http://www.conversationmarketing.com/2011/04/linkscape-google-spreadsheets.htm The first article references the second and third article.  The second article talks about how to use spreadsheets to scrape sites (include google SERP).  The third article mentions automatically grabbing data once a mont or so.  Seems like you could get a solution for what you are looking for with these three articles.
