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.
