According to bug 1193222, comment #13, I need to install powerd in order to get the screen to sleep on inactivity if I use Mir (the default for Saucy) as display manager.
But if I try to install powerd, modemmanager gets removed:
till@till-twist:~$ sudo apt-get install powerd

This means that I can either have the feature of the screen going to sleep or cellular data support, not both.
