Execution order of controls rb files

Hi,

I would like to how i can configure the execution order of the rb files in controls directory.
I tried to name the filenames in numerical order but i does not work. E.g 1-file.rb 1-1-file.rb 1-3-file.rb

anyone can advise me what i can do to make sure that the rb files are executed based on the order i want?

Thanks
