OCD is characterized by routines undertaken due to beliefs like, "If I don't wash my hands 3 times before I leave the house then my mom will get breast cancer."

If we're talking mental health, ADHD, autism spectrum disorder (ASD), and OCPD all can also show characteristics of preferring things to be ordered and in line; see for example https://www.healthline.com/health/obsessive-compulsive-personality-disorder about OCPD.

If we're talking subclinical personality traits, the Myers-Briggs "J" people tend to be more "gotta be organized" than the "P" people, though the latest thinking in personality typing is quite a bit more complicated, as you can read about https://www.alittlebitofpersonality.com/

Finally, of the "big 5" personality traits, orderliness is associated with conscientiousness: https://en.wikipedia.org/wiki/Hierarchical_structure_of_the_Big_Five
