Script tags are run (though not necessarily "downloaded")
sequentially. So as long as the script tag for the "library" is before
the call to the function in the "library" you shouldn't have any
problems.
For example, the following works:
<script src="somelibrary.js"><script>
<script>somelibraryfunction()</script>
However this won't work:
<script>somelibraryfunction()</script>
<script src="somelibrary.js"><script>
jQuery's $().ready shouldn't change the outcome.
If that doesn't solve the problem then you'll need to show a
non-working example.

I think* that's the key. Although they are run sequentially, js does not
wait for complete loading of one library before moving onto process the
next. So when you have a slow connection it seems to be possible that
the call to somelibraryfunction() fails.

It shouldn't happen. Can you post the source for the page(s)? Or at
the very least post the order of the JavaScript files. Such as:
<script src="jquery.js"></script>
<script src="library.js"></script>
<script>$(function() { failingFunction(); } );</script>
