With the use of arXiv DOIs, we are starting to have records in ADS with multiple DOIs.
Our system is able to deal with them (the doi field in SOLR is multi-valued), but we want the publisher DOI (in particular the VOR) to be the first one in the list, since this one is used to link to the article in the UI.
This PR changes the policy for merging DOI metadata by adding a priority sort based on the origin of the relevant metadata.
