Comment 2 for bug 1321017

Here's a fix for the inner-most query generating sub. From the commit message:

    Previously, in some cases (often needlessly) we oredered constituent
    records within a metarecord by a combination of type/form/blvl. This
    is not only of little use, but also expensive. Instead, order them
    by the bib's calculated quality, which takes type/form/blvl into account
    already.

    Also, use the new metabib.record_sorter to find the title tie-breaker
    instead of using the view-of-a-view-of-a-view mrd compatability shim.

    The net result is several orders of magnitude speed increase for constiuent
    record retrieval.
