Just a quick and dirty approach without the need of writing a macro:

You may use the "Color Transformer" plugin to transform your
RGB-image to the corresponding Lab-stack. Then convert the stack to
an 8 bit stack (well this may lead to a loss of valuable
information). Finally select a region of interest and call "Color
Histogram" and finally copy the histogram values.
