You don't mention what OS you're running, but I'd guess it's 10.8 or 10.9. Preview is now sandboxed. Sandboxed apps must be passed a file object, not a path. From the AppleScript release notes for 10.8:

> When sending commands to a sandboxed application, such as TextEdit in OS X Mountain Lion, parameters that refer to files must be of an explicit file-like type and not a bare string, or the target application will not be able to access the file. For example, file "Macintosh HD:Users:me:sample.txt", POSIX file "/Users/me/sample.txt", or the result of choose file would all be acceptable, but the string "/Users/me/sample.txt" would not.
