It's monted on the root FS, which is just 'rw'. I also tried running the binary by hand and I can:

$:.../extensions/Scribunto/engines/LuaStandalone/binaries/lua5_1_5_linux_64_generic# ./lua Lua 5.1.5 Copyright (C) 1994-2012 Lua.org, PUC-Rio >

Even as the 'www-data' user I can run that binary.

That would happen on any page that contains the invoke command.
