Pgfplots - "reverse legend" by Lua

Hello,

one more question about pgfplots & Lua:

how to specify "reverse legend" by Lua?

Here are some examples:

- Plot 1 contains no Lua code and gives the desired result (OK);
- Plot 2 uses Lua to specify "legend entries" successfully (OK);
- Plot 3 tries to use Lua to specify "reverese legend", but doesn't work;

----
\usemodule[pgfplots]

\starttext
   Plot 1 -- OK

   \starttikzpicture
     \startaxis[legend entries={Cos,Sin2,Sin},reverse legend]
       \addplot+[mark=none,fill,green]{cos(deg(x))}\closedcycle;
       \addplot+[mark=none,fill,yellow]{0.5*sin(deg(0.5*x))}\closedcycle;
       \addplot+[mark=none,]{sin(deg(x))}\closedcycle;
     \stopaxis
   \stoptikzpicture

   Plot 2 -- Legend by Lua -- OK

   \starttikzpicture
     %\startaxis[legend entries={Cos,Sin2,Sin}]
     \cldcommand{startaxis{["legend entries"] = "{Cos,Sin2,Sin}"}}
       \addplot+[mark=none,fill,green]{cos(deg(x))}\closedcycle;
       \addplot+[mark=none,fill,yellow]{0.5*sin(deg(0.5*x))}\closedcycle;
       \addplot+[mark=none,]{sin(deg(x))}\closedcycle;
     \stopaxis
   \stoptikzpicture

   Plot 3 -- Reverse legend by Lua -- not working

   \starttikzpicture
     %\startaxis[legend entries={Cos,Sin2,Sin},reverse legend]
     \cldcommand{startaxis{["legend entries"] = "{Cos,Sin2,Sin}", "reverse legend"}}
       \addplot+[mark=none,fill,green]{cos(deg(x))}\closedcycle;
       \addplot+[mark=none,fill,yellow]{0.5*sin(deg(0.5*x))}\closedcycle;
       \addplot+[mark=none,]{sin(deg(x))}\closedcycle;
     \stopaxis
   \stoptikzpicture
\stoptext
----

So how to make Plot 3 work?

Best regards,

Lukas
