This bug still exists in Maverick.
I've compared index.theme from custom theme (~/.themes/<custom_theme>/index.theme) with original Radiance index.theme (/usr/share/themes/Radiance/index.theme). The original file has line "ButtonLayout=close,minimize,maximize:" while custom doesn't. I suppose gnome-appearance-properties should have copied that line to the custom theme file.
As a workaround you can add this line to your custom index.theme manually.
