I had to enable autosaving in the Retroarch config file before this worked (from the retroarch sample conf):
# Automatically saves a savestate at the end of RetroArch’s lifetime.
# The path is $SRAM_PATH.auto.
# RetroArch will automatically load any savestate with this path on startup.
# savestate_auto_save = false
So adding ‘savestate_auto_save = true’ to ~/RetroPie/configs/all/retroarch.cfg will tell retroarch to automatically save the SRAM when exiting.
