Ability to search via score

Is there a possibility to search for images with the highest score in descending order, And/or a popular list with an "All Time" option?

Please forgive me if I have missed it, but I have been searching for quite some time.

Typing order:score automatically sorts all posts by score in descending order; if you want to reverse the order, order:score_asc.

Thank you. Is there a place to view non-standard tags?

You can also do a search like score:>=10. And yes, click "help" on the posts page, then "cheat sheet".
