Select the Windows button and then select All Apps. Don't select the menu in between.
After you get to All Apps, click on Microsoft Office (to show the individual programs) and then right click on one of the programs; you should see "pin to Start" as one of the options. Click on that and it should show up.
It's possible that 10122 will show the individual programs in Office in the alpha listing of All Apps. If this happens, do the same as you did above.
If you'd like to do everything in (almost) one fell swoop, Pick an individual Office program, right click on it and select "Open File Location. There, you'll see all the individual programs; just right click on each one and select "Pin to Start". Although it still has to be done individually, it's much faster this way. :)
I use this last "option" to pin stuff to my Quick Launch Bar.
