specific mod_rewrite case

I migrated blogs from serendipity to wordpress. In doing so, I went from one url schema to another.

Serendipity:

http://example.com/index.php?/archives/111-Example-title!-of-POst.html

Wordpress:

http://example.com/example-title-of-post/

Notice that it needs to have caps removed and all punctuation except the '-' removed from the URL. Now the nearest I can come up to with this is the following:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^index.php\?/archives/([0-9]+)-(.*)\.html$ http://linux-blog.org/$2/ [R=301,QSA,L]
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

The most important line being: RewriteRule ^index.php\?/archives/([0-9]+)-(.*)\.html$ http://linux-blog.org/$2/ [R=301,QSA,L]

OF course, this doesn't work at all. Can someone point me in the right direction?
