Switch tabs in XCode "Organizer"

Question

Dear everyone,
I recent wrote a very small AppleScript as part of my whole automation script. What I wanna do it start Xcode -> choose "Window" from the menu -> click on "Organizer" from the menu -> click on "Device" button from "Organizer" -> choose "Editor" from menu -> Click on "Refresh from Developer Portal". The incomplete code is provided in the following.
Actually the only problem I have got so far is this step "click on "Device" button from "Organizer"" because sometime the focus is not on "Device" but other tabs (don't know how to attach a screenshot to this forum) and I have no idea of how to switch between them. I know I can use "Select Next Tab" menu item to switch to the next one but how to decide which tab (maybe by tab name) I have already switched to?
Actually I even do not know whether I should call them "tabs". They maybe "button". I tried using "button" but it did not work for it.
Any hint is much appreciated!
Cheers
Daniel

Hi Gamelot,
That solved my problem. Thanks a lot for that. "tool bar" should be used in that case.
BTW, do you know anywhere to know more about the terminologies used in AppleScript?
The whole code is:
tell application "Xcode" to activate
#Activate "Organizer"
tell application "System Events"
          tell process "Xcode"
                    tell menu bar 1
                              tell menu bar item "Window"
                                        tell menu "Window"
                                                  click menu item "Organizer"
                                        end tell
                              end tell
                    end tell
          end tell
end tell
delay 2
tell application "System Events"
          tell process "Xcode"
                    click button "Devices" of tool bar 1 of window 1
          end tell
end tell
#Refresh the provisioning profile
tell application "System Events"
          tell process "Xcode"
                    tell menu bar 1
                              tell menu bar item "Editor"
                                        tell menu "Editor"
                                                  click menu item "Refresh from Developer Portal"
                                                  delay 2
                                                  keystroke (ASCII character of 13)
                                        end tell
                              end tell
                    end tell
          end tell
end tell
