1) mapType TERRAIN does not working. The only working type of map is Roadmap
You are right, this is a bug. To fix it open the snippet.gmaps.txt file and replace the line 57:
$cfg['mapType'] = (($mt == 'ROADMAP') || ($mt == 'SATELLITE') || ($mt == 'HYBRID') || ($mt == 'TERRAIN ')) ? $mt : 'ROADMAP';
by:
$cfg['mapType'] = (($mt != 'ROADMAP') && ($mt != 'SATELLITE') && ($mt != 'HYBRID') && ($mt == 'TERRAIN ')) ? 'ROADMAP' : $mt;
If have updated the demo site with this fix. see

2) Ajax infowindow douse not working there is some javascript error
On my side I haven't js errors. I use
[!Gmaps? &mapWidth=`100%` &mapHeight=`400px` &mapType=`TERRAIN` &mkrClick=`link` &mkrOver=`info` &mkrIconTv=`mkrImg` &infoboxAjaxId=`241` &markers=`c298`!]
And on page 241:
[!GmapsInfobox? &mkrTextTv=`mkrContent`!]
Check that your document #271 uses a blank template.
Which kind of js errors do you get ? I don't see a js error on your site.
3) scalable NO does not working. The map is always scalable
The behaviour is the same as on the google V3 demo site.
Follow the "hello world" demo link at
http://code.google.com/intl/en-EN/apis/maps/documentation/javascript/tutorial.html
and look at the code source ( meta name="viewport" content="initial-scale=1.0, user-scalable=no" )
I can't do better than google maps
