Rajesh was intrigued to find the scroll bar on the left of his screen for Google Arabic search and I agree with his observation. Now I am no UI design expert but for languages that are written from right to left is it imperative that the readers are left-handed (no pun intended) too? Also notice how the left/right arrow keys behave on the page. The reasons for the text alignment has been explained but any rationale for the scrollbars?
