It is silly. Clicking on one of your "lj meta" tags loads this URL:
http://www.livejournal.com/users/serenejournal/tag/lj+meta, which, as you've observed, doesn't work.
However, all is not lost! The "equivalent" URL http://www.livejournal.com/users/serenejournal/tag/lj%20meta (http://www.livejournal.com/users/serenejournal/tag/lj%20meta) does work—try it and see! %20 is "URL encoding" for a space character. Plus is supposed to be shorthand for a space, too, I don't know why it doesn't Just Work.
Without knowing anything else about LiveJournal's tag system, based on that quick experiment I'd be reasonably confident that it's a bug which will be fixed at some point. So, don't go changing your tags, is my advice.
