Why not use daemon for the stopping and add a status task also?

    task :stop, :roles => clockwork_roles, :on_no_matching_servers => :continue do
      run "daemon --inherit --name=clockwork --env='#{rails_env}' --output=#{log_file} --pidfile=#{pid_file} -D #{current_path} --stop || true"
    end

    desc "clockwork status"
    task :status, :roles => clockwork_roles, :on_no_matching_servers => :continue do
      run "daemon --inherit --name=clockwork --env='#{rails_env}' --output=#{log_file} --pidfile=#{pid_file} -D #{current_path} --verbose --running || true"
    end

I or || the command with true because I don't want cap to fail if the process is not running. Another change I made was I had my log_file use shared_path instead of current_path. Thanks for giving me something to start with. Of course, I had to sudo apt-get install daemon on my servers first.
