It's not always possible to include all script in the markup.
If the script depends on dynamic data then you'll need to "inject" the script from the code behind.

My rule is to always try to avoid "injecting" script from code behind if possible and only use that as a last resort.

Edit:
Using scriptmanager is prefered if you have many different script files.
When using scriptmanager all scripts will be "concatenated" into a single file. This has an impact on how the browser downloads the scripts. Browsers usually have a limit of 2 concurrent connections and if you have 10 scripts then you'll need to download them all in 5 steps. Scriptmanager will see to it that it all happens in a single step.
