I made this dice pyramid that I want to light from inside with
incandescent bulbs and I bought this radio shack 12.6 volt xformer,
but it has a "center tapped secondary" and I don't know what that
means or how to wire it to power some 12 volt bulbs.

can anybody help?

You just ignore the center-tap (do not connect it). I assume you know that
the transformer current/power rating must not be exceeded or it will get too
hot and self-destruct!

The secondary winding has a centre tap (a connection in the middle) so
that between either end of the secondary and the tap you would measure
6 volts.

Just ignore it and wire your bulbs to the other two secondary
connections.
