Looks like a doc error and a logging error (BUG instead of ERROR).

It should be:
@msg.header["h_name"]
or
@msg.header["h_name"][number]  (selects the "number" h_name)

You could also use the @msg.h["..."] shortcut (IIRC is equiv to
@msg.header).

See
http://sip-router.org/docbook/sip-router/branch/master/select_list/select_list.html#select_list.core
(they should be up-to-date and correct and the name is mostly
self-explaining)
