When a record match set's quality metrics include one based on MARC tag, subfield, and value, the value from the quality metric is compared with the value taken from the MARC record (either incoming or already in the database).
However, the value from the MARC record is sent through NACO normalization (unless it's from an 020, 022, or 024 field), while the value from the quality metric is _not_ normalized.
Consequently, unless the value in the metric is already in lowercase and sans punctuation, it likely will not match anything in the MARC record, thereby reducing the accuracy of the quality measurement.
