I liked John Sauer's approach so much I wrote myself some getters/setters for these properties using his approach. It's works well because you do not have to activate iTunes before using them. Anyway, I thought I'd post them in case they're of help to anyone. You will get or set their values using the "types" (modeled after the menu item names) as follows:

Repeat types are "Off", "All", or "One".

Shuffle types are "Off", "By Songs", "By Albums", or "By Groupings"

on getRepeatType() -- the return value is a string: Off/All/One
    tell application "System Events"
        tell process "iTunes"
            set menuItems to menu items of menu bar 1's menu bar item "Controls"'s menu 1's menu item "Repeat"'s menu 1
            set currentChoice to "unknown"
            repeat with anItem in menuItems
                try
                    set theResult to value of attribute "AXMenuItemMarkChar" of anItem
                    if theResult is not "" then
                        set currentChoice to name of anItem
                        exit repeat
                    end if
                end try
            end repeat
        end tell
    end tell
    return currentChoice
end getRepeatType

on setRepeatType(repeatType) -- repeatType is a string: Off/All/One
    set currentValue to my getRepeatType()
    ignoring case
        if currentValue is not repeatType then
            tell application "System Events" to tell process "iTunes"'s menu bar 1's menu bar item "Controls"'s menu 1's menu item "Repeat"'s menu 1
                if repeatType is "all" then
                    perform action "AXPress" of menu item "All"
                else if repeatType is "one" then
                    perform action "AXPress" of menu item "One"
                else
                    perform action "AXPress" of menu item "Off"
                end if
            end tell
        end if
    end ignoring
end setRepeatType

on getShuffleType() -- the return value is a string: Off/By Songs/By Albums/By Groupings
    tell application "System Events"
        tell process "iTunes"
            set menuItems to menu items of menu bar 1's menu bar item "Controls"'s menu 1's menu item "Shuffle"'s menu 1
            set onOffItemName to name of item 1 of menuItems
        end tell
    end tell

    -- is shuffle off
    ignoring case
        if onOffItemName contains " on " then return "Off"
    end ignoring

    -- shuffle is on so find how we are shuffling
    set currentChoice to "Unknown"
    tell application "System Events"
        tell process "iTunes"
            repeat with i from 2 to count of menuItems
                set anItem to item i of menuItems
                try
                    set theResult to value of attribute "AXMenuItemMarkChar" of anItem
                    if theResult is not "" then
                        set currentChoice to name of anItem
