Hi Peter,
You are right we should include ScriptLoader in the printerfriendly skin, I will do that going forward. All skins should include that. I don't think it is missing in any other skins we ship.
I'm not able to produce the script error you mentioned about search results, but if it is causing you a problem you can change back to an older version of jQuery by overriding these in user.config
<add key="GoogleCDNjQueryVersion" value="1.5.2"/>
<add key="GoogleCDNjQueryUIVersion" value="1.8.11"/>
you can specify older versions if you have any custom script that is not compatible with the latest jquery.
Best,
Joe
