Deployment of Turkish Language Pack using GPO shutdown script

Question

Running the following command through cmd installs the desired language pack successfully on a client machine with Office 2010:
\\server\share\Office\setup.exe /config
\\server\share\Office\OMUI.tr-tr\config.xml
The question now is "How can I deploy the language pack via GPO?"
I'm using the following batch to deploy office 2010 in my environment, so far my attempts to deploy the language pack using a modified version of this batch failed...
What would I need in this batch file to achieve language pack deployment? 
setlocal
REM *********************************************************************
REM Environment customization begins here. Modify variables below.
REM *********************************************************************
REM Get ProductName from the Office product's core Setup.xml file, and then add "office14." as a prefix.
set ProductName=Office14.PROPLUS
REM Set DeployServer to a network-accessible location containing the Office source files.
set DeployServer=\\xx\Office2010SourceFiles32bit
REM Set ConfigFile to the configuration file to be used for deployment (required)
set ConfigFile=\\xx\Office2010SourceFiles32bit\ProPlus.WW\config.xml
REM Set LogLocation to a central directory to collect log files. (the user doing the install needs write access)
set LogLocation=\\xx\Office2010LogFiles32bit
REM *********************************************************************
REM Deployment code begins here. Do not modify anything below this line.
REM *********************************************************************
IF NOT "%ProgramFiles(x86)%"=="" (goto ARP64) else (goto ARP86)
REM Operating system is X64. Check for 32 bit Office in emulated Wow6432 uninstall key
:ARP64
reg query HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432NODE\Microsoft\Windows\CurrentVersion\Uninstall\%ProductName%
if NOT %errorlevel%==1 (goto End)
REM Check for 32 and 64 bit versions of Office 2010. (Office 64bit would also appear here on a 64bit OS)
:ARP86
reg query HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\%ProductName%
if %errorlevel%==1 (goto DeployOffice) else (goto End)
REM If 1 returned, the product was not found. Run setup here.
:DeployOffice
start /wait \\xx\Office2010SourceFiles32bit\setup.exe /adminfile \\xx\Office2010SourceFiles32bit\updates\office2010custom32bit.msp
echo %date% %time% Setup ended with error code %errorlevel%. >> %LogLocation%\%computername%.txt
REM If 0 or other was returned, the product was found or another error occurred. Do nothing.
:End
Endlocal
Ideally what I want to achieve at start up is to check for Office 2010, deploy Office 2010 if it's not already deployed, check for language pack, deploy language pack if it's not already deployed.
Thanks
