You might have a problem with that script, if any of your wp_options have a
serialized string containing the url (like an rss feed url), since the
length of the string will no longer match the serialized string length
value. If so, you might want to only replace a few known records in the
wp_options table which have the entire unserialized string)
Also, look at the guid field in your posts table, to see if you have the old
url in there as well.
(We use wp-mu still, so my scripts are a little different, but we handle
those 2 cases I mention above in addition to yours. We also search/replace
in the wp_blogs and wp_site tables)
Just a thought,
