it's ok with TL 2014 (and the latest luatex from experimental),
that has
\def\pgfversion{3.0.0}
and it should be the
http://sourceforge.net/projects/pgf/



but
downloading the pgf module from  the garden

78     % Patch some configuration macros such that the modifications are
79     % available in LUA as well:
80     \pgfkeys{

code={}{\directlua{pgfluamathfunctions.setTrigFormat("deg")}\aftergroup\pgfmath@settrigformat

82      /pgf/trig format/rad/.add
code={}{\directlua{pgfluamathfunctions.setTrigFormat("rad")}\aftergroup\pgfmath@settrigformat

83     }
84     % ... and reactivate the key:
85     \pgfmathiftrigonometricusesdeg{%

and
\def\pgfversion{3.0.0-cvs}

So it seems that the cvs version is not ok with ctx
and I think that these
74       pgfluamathfunctions = require("pgfluamath.functions")
75 >>    pgfluamathparser = require("pgfluamath.parser")}
are also wrong in Lua .
