Suggestion to improve subtitle sorting

I like this addon, but I think there should be a sorter to improve subtitle selection and make it easier. I have a simple modification for it. You can try it out by modifying this function in the subtitledownloader file. Here is the modification I made:
def list_subtitles(self):
    from difflib import SequenceMatcher

    release_groups = [
        ['bluray', 'bd', 'bdrip', 'brrip', 'bdmv', 'bdscr', 'remux', 'bdremux', 'uhdremux', 'uhdbdremux', 'uhdbluray'],
        ['web', 'webdl', 'webrip', 'webr', 'webdlrip', 'webcap'],
        ['dvd', 'dvd5', 'dvd9', 'dvdr', 'dvdrip', 'dvdscr'],
        ['scr', 'screener', 'r5', 'r6']
    ]
    release = []
    for group in release_groups:
        release.extend(group)
    release.extend(['avi', 'mp4', 'mkv', 'ts', 'm2ts', 'mts', 'mpeg', 'mpg', 'mov', 'wmv', 'flv', 'vob'])

    quality_groups = [
        ['4k', '2160p', '2160', '4kuhd', '4kultrahd', 'ultrahd', 'uhd'],
        ['1080p', '1080'],
        ['720p', '720'],
        ['480p'],
        ['360p', '240p', '144p'],
    ]
    quality = []
    for group in quality_groups:
        quality.extend(group)

    audio_groups = [
        ['dts', 'dtshd', 'atmos', 'truehd'],
        ['aac', 'ac'],
        ['dd', 'ddp', 'ddp5', 'dd5', 'dd2', 'dd1', 'dd7', 'ddp7'],
    ]
    audio = []
    for group in audio_groups:
        audio.extend(group)

    color_groups = [
        ['hdr', '10bit', '12bit', 'hdr10', 'hdr10plus', 'dolbyvision', 'dolby', 'vision'],

    for subtitle in self.subtitles:
        attributes = subtitle["attributes"]
        language = convert_language(attributes["language"], True)
        log(__name__, attributes)
        clean_name = clean_feature_release_name(attributes["feature_details"]["title"], attributes["release"],
