I need to export job scripts on an individual basis, say job ID 5. How do I do this? The only approach I know of is to create a new job on a different server, manually set all the job parameters, then "cut/paste" or "export/import" the script. This is too much overhead for moving a script from a Dev or QA server to a Production server, and increases the probability of error.

If you are on version of 3.2 or later you can replicate jobs and settings between different environments using jobs, That's it, use "Copy jobs to remote 24x7 Scheduler" job template from the "Advanced Job Management" section to create a job for replicate other jobs and folders to remote instances.

Back to your question about the Script Library, if the goal is the same use "Copy settings …" template. In the generated job change options to replicate only the Script Library"

You can disable such maintenance jobs so they can be run only manually or delete them after the replication if this is just one time deal.
