Apple script for plist modify not working in MacOS mavericks

Question

I just updated my Mac OS to Mavericks and stuck in a issue in my project.

I an updating localization key in plist with apple script. But when I set the localization key plist file goes to 0 KB.

It was working in Mac OS 10.8.

Below is my script to change plist key :

 if keyVar as string = "CFBundleLocalizations" then
                        -- Parse the string for delimiter , and get the array of schemes
                        set AppleScript's text item delimiters to ","
                        set theLanguageItems to text items of valVar
                        -- restore delimiters to previous.if not reset then creats error for below code if we have any property below CFBundleLocalizations propert file.
                        set AppleScript's text item delimiters to "="
                        --if there are localization available 
                        if the length of theLanguageItems is greater than 0 then
                            --create structure for CFBundleLocalizations 
                            tell application "System Events"
                                set pFile to property list file plistFile
                                tell pFile
                                    tell contents
                                        --and write to the plist file                                   
                                        --make new property list item with properties {kind:list, value:"theLanguageItems"}
                                        set value of property list item "CFBundleLocalizations" to theLanguageItems
                                    end tell
                                end tell
                            end tell
                        end if

In Mavericks it seems behavior difference for AppleScript, where set value of property list item is not working as expected.

One alternate is to use make new property that you have commented. In this case a new property will be created and appended to the existing one. Hence you need to be careful for that.

Below is actual solution that works for array list

 repeat with theCurrentValue in theLanguageItems
     make new property list item with properties {kind:string, value:theCurrentValue}
 end repeat
