require 'rake'

Rails.app_class.load_tasks

Once the rake task is invoked in this context, Rails will prevent it from running again unless you specifically re-enable it.

class Test
  def perform
    Rake::Task['crono:hello'].reenable
    Rake::Task['crono:hello'].invoke
  end
end

See this blog post for a little more detail.
