new bootstrap mechanism - .nocache.js

that you need in the <head> (like the Google Maps API <script>) must
be placed before the GWT script - by putting it in the <body>, there's
no chance of weird errors happening when you put the <script>s in the
incorrect order. I've seen people do both and say it works fine, but
I don't know enough about JS and how browsers load libraries to know
what the difference would be.

as krispy said, it doesn't really matter. But take a look at that:

Yahoo suggests putting JavaScript as low as possible inside your HTML
page for performance reasons. Interesting point.

As Max and krispy mentioned, your GWT application should load whether the script tag is in the head or in the body.
However, Max raises an interesting point in that having the script tag as low as possible in your HTML page leads to better performance in application loading. In fact, this is the reason why the FAQ you referenced above suggested adding the script tag to your <module>.nocache.js in the body. That said, the 1.4 applicationCreator script should also include the script tag in the body to improve performance.
I've create a new report (issue #1600) for this on the Issue Tracker to have it fixed for 1.5:

It's also worth mentioning that if your static HTML doesn't render anything before calling into GWT, the section you choose to include the script tag won't affect load time performance.
