I would use a tool specific database table [0] rather than the local files system mostly to avoid using NFS to save state. Otherwise this is not a horrible practice. The token that your app receives is only valid in combination with the app's secret key. You should do anything you can to prevent it from being leaked to other users of the application as that would allow them to impersonate the true owner. Storage in a database table that is owned by your tool and not readable by other tools or as you are doing in a file if that file is not world readable are reasonable precautions. Fundamentally you should treat the user's OAuth token the same way you would treat the password for a bot account or any other authentication secret.
