HTML SELECT with text-align: right; does not work in Internet Explorer

I have an HTML SELECT that needs to be right-aligned. When I use text-align: right; it works in Firefox, but not in IE.

I googled a bit and the options I had were:

1. Complete the left side with blank spaces;
2. Use dir="RTL";
3. Use a DHTML select.

I'm not allowed to use solution #2. Solution #1 is a bit messy. Can't use Solution #3 either, unless there's a way to make the DHTML select look exactly like the regular HTML select.

Are there any other ways I could do this?

Thanks!
