The scripts seem to be sane and not clobber anything, so I'd put them in 
/etc/profile.d

You will need to log out and then back in again for them to take effect.

That site doesn't explicitly mention /etc/profile.d, but if you look in 
/etc/profile, you'll see that that script runs all the scripts within 
/etc/profile.d itself.
