This won't work exactly as shown. Every single blog post I have seen on the subject is wrong because they are only taking into account the normal search results. universal search results will make that data collected look all haywire because the cd= parameter can be used to show ranking within a set of sitelinks or in universal local, ect results.

Each non-normal SERP ranking with the cd= parameter also has an additional parameter marking it as part of universal search. You will need to take that into account to get the data right.

Do a search that products site links for a site and compare every sitelink and all their parameters to the normal SERP parameters and you will see what I mean.
