I am trying to load both the maps library and the places library with javascript so I can embed a map into my page, use google.maps.geometry.spherical functions and make pla
The first script doesn't point to a javascript, this will try to load the maps-homepage as a script(of course this will fail).
There is no need to include multiple scripts, simply use:
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?libraries=geometry,places&sensor=false">
This will load the maps-API(V3) and includes the places+geometry-libraries
https://developers.google.com/maps/documentation/javascript/libraries?hl=en
However, as Colin said, this looks like V2-code.
You can use it in this way
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=YOUR_KEY&libraries=places"></script>
