are external javascript files loaded sequentially or parallel?

if i have multiple script tags in my page like:

    <script src="js/jquery-1.7.min.js" type="text/javascript"></script>
    <script src="js/jquery.jplayer.min.js" type="text/javascript"></script>
    <script src="js/globals.js" type="text/javascript"></script>
    <script src="js/sound.js" type="text/javascript"></script>

can i rely on the fact that code from the previous ones is already available when the latter ones are loaded?

They may be loaded (via the network) in parallel, but they are evaluated in sequence.

So yes, you can rely on the order.
