Comment 2 for bug 1302207

On a related note, we have noticed that sometimes the ISBN/ISSN/UPC that apparently gets used is inconsistent. I think the branch below will generally ensure that the identifiers are returned in the order they were originally found in the record, so the first one would be the one used for lookups (at least when only one is used).

There may be other/better ways to do that, especially if we are cleaning up ISBNs in other ways first that may be changing more in that area, so I am just throwing this out here for now.
