AppleScript won't keystroke "22.com"? I've tried coding it in different ways, but no matter what I do it will not type "22.com".
I've found that trying to keystroke with a large number of characters is highly unreliable. It doesn't seem to wait for every character to be typed before returning. I'd suggest trying this workaround I've been using:

on keystroke_string_(keystr)
    tell application "System Events"
        repeat with _character in keystr
            keystroke _character
        end repeat
    end tell
end keystroke_string_


That'll iterate through the characters, and press each one manually. I've found that this works nicely with any length of string.
