This is on a 2012 MacBook Air.
I just used Disk Utility and erased the SSD, booted into Internet Recovery, connected to the network and let it do its thing. Its prompting me to install Lion. From this point, how can I perform a fresh install of 10.9.4?

Do you have a Mavericks recovery partition? Or is Internet Recovery your only option?

To reinstall Mavericks, you can either create Mavericks recovery media or install Lion and upgrade to Mavericks.
