I wrote a script that will upvote all job postings containing a salary range:

I've tried to make it comprehensive, and it supports a few different formats, but if it doesn't catch something it should (or it upvotes something it shouldn't), let me know. It throttles to 1 vote every 2s as to be nice to the HN servers.
To use it, just copy-paste the code itself into your browser's JS console. Hope this is helpful!
