If you're using the same hook location then you should probably just use one plugin. But if you want to use two for whatever reason, then you should set the execution order fields so that they run in the order you expect.

But if you've created a php file called oftw.php, then you may not need to use plugins at all, just put the code you need in the file. There's nothing magic about a plugin, it just lets you add code without editing the existing php files.
