A competitive keyword ranks on the first page in Google for allintext, allinanchor and allintitle, but allinurl is around #200. My site shows up around #200. Is it because my allinurl is so low, or am I sandboxed?
Allinurl isnt important. Typically what your allinanchor shows is a good indication of where your site will rank assuming you are not either sandboxed or penalized. After anchor IMHO the most important one would be title and then text.
Yea keywords in the URL aren't valued very much, they help of course but don't really do anything you can notice.
