if you re-enable loading of l-lua.lua in
texmf-context/tex/generic/context/luatex/luatex-fonts.lua and
rebuild the format, your example should work again:

    --- luatex-fonts.lua.orig	2013-02-12 13:10:42.903959955 +0100
    +++ luatex-fonts.lua	2013-02-12 13:11:21.488379154 +0100
    @@ -132,7 +132,7 @@
        -- to using luatex-fonts with luatex-fonts-merged.lua and forget about the rest. The following
        -- list might change without prior notice (for instance because we shuffled code around).
    
    -    ----------("l-lua.lua")
    +    loadmodule("l-lua.lua")
        loadmodule("l-lpeg.lua")
        loadmodule("l-function.lua")
        loadmodule("l-string.lua")
