These scores are calculated for each continuing resources (type of record (LDR/6) is language material ('a') and bibliographic level (LDR/7) is serial component part ('b'), integrating resource ('i') or serial ('s')).
The calculation is based on a slightly modified version of the method published by Jamie Carlstone in the following paper:
Jamie Carlstone (2017) Scoring the Quality of E-Serials MARC Records Using Java, Serials Review, 43:3-4, pp. 271-277, DOI: 10.1080/00987913.2017.1350525 URL: https://www.tandfonline.com/doi/full/10.1080/00987913.2017.1350525
