Rails routing - redirection with block AND status code

Well, I've been hitting my head against a brick wall with this one - any
help much appreciated!

I'm redirecting old urls in my routes.rb file and for the most part
that's working well, e.g.:

match '/pages/holiday-specials/', :to => redirect( "/accommodation",
:status => 301 )

However, I need a special catch-all rule that needs to do some regex
checking, so I have a final rule which contains a block. The code below
works well EXCEPT I can't get it to pass the status, no matter what
combination I try.

match '/*:path', :to => redirect( lambda { |params|
"/operator/#{/[^\d](\d+)([^\d]|$)/.match(params[:path])[1]}" }, :status
=> 301)

Any ideas? How do you perform a redirection with a block AND status
code?

Never mind. Worked it out. Actually I had another rule that was being
matched first and it wasn't doing a 301 redirect.
