Running shell from applescript

Question

Hi all,
does anybody knows why inside my applscript a script won't run properly while it will if called from the terminal?
one example
do shell script "directory/myscript.sh"
will not work, while
tell application "Terminal"
  activate
          do script "directory/myscript.sh"
end tell
will work perfectly?

thanks a lot guys, you're saving me, because I'm in a *real* hurry...
can you help me launch this from an applescript?
