That score comes from 7 science badges — Star, Distant (over 1,000 light-years), On the zodiac, Hot blue B-type star, Giant star, Blue-white star and Intrinsically luminous (Mv < −2) — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
