on Aurora (which will be Fx 6) when I use it via Stylish.
I stopped using userChrome.css because Stylish lets you see changes without having to restart each time.
Sorry that I can't help with your specific question of userChrome.css and Fx5 portable.
I now tried your code with portableapps.com Fx5 (on Win XP SP3) and it works just fine though I did find a couple of errors in the Error Console.
A couple of differences that may or may not be relevant:
My install path is:
E:\PortableApps\FirefoxPortable
My userChrome.css has this location:
E:\PortableApps\FirefoxPortable\Data\profile\chrome
There is nothing in the userChrome.css file except this (= what you provided):
@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");
#browser { -moz-box-direction: reverse;}
I have side-bars off by default.
With the userChrome.css file in place, I opened Fx5 and immediately checked the Error Console. The two errors are below:
Could not read chrome manifest file 'E:\PortableApps\FirefoxPortable\App\firefox\extensions\{972ce4c6-7e08-4474-a285-3208198ce6fd}\chrome.manifest'.
Warning: XUL box for _moz_generated_content_after element contained an inline #text child, forcing all its children to be wrapped in a block.

I cleared the console and closed it (the console, not the browser). I then went to Alt, View, Sidebars, Bookmarks and the bookmarks sidebar opened on the right of the screen as you require.
I looked at the Error Console. At this point, there were no errors.
Hope this helps.
