1) (not totally sure about this) try adding "api: true" to autoscroll (the last plug in)
2) try replacing the "s" with 10000 (just to be sure)
3) maybe use the ID to select the scroller (#logos-scroll)
4) (if not used already) use "var api" instead of logos. Somehow this solved things for me in the past...

Indeed.
I too am searching for the un-minimized source.

Also pretty useful for debugging by users...

I believe this is not your fault, but a jQuery Tools bug.
In the jQuery line 2447: if ( !handler.guid )
the handler is not optional.
However, searching through the jQuery tools code (v.1.1.2), the third variable (handler) is not always passed!
(If you firebug the jQuery Tools webpage, the error (because of minimized jQuery it's "H is undefined") shows up all over the place!!!)
Strangely, nothing is mentioned about this (even on the forums!)
