Not too many people know about Digital Mars implementation, so I figured I'd let you know, it may help in your endeavor somehow.

http://www.digitalmars.com/dscript/index.html

"

	DMDScript is Digital Mars' implementation of the
	ECMA 262
	scripting language. Netscape's implementation is called _javascript_,
	Microsoft's implementation is called JScript.
	DMDScript is much faster than other implementations, which
	you can verify with the included benchmark.

DMDScript is implemented in the D Programming Language. (A C++ implementation is also available.)"

Also it is possible to implement dynamic languages using the .NET runtime.  (www.smallscript.org) , so along with Parrot, that could be another option for you if you change your mind about using Lua.
