"If the wraps are aligned (as molded) and shown in the instructions, the vertical half round wood tunnels may not line up between the Inter Tank and Inter Stage vacu-form wrap locations!"

That description is a little confusing. The dowels will line up if built as is and by the instructions, but most of the interstage wrap will end up rotated 1/4 turn to the left.
Notice the illustration below - At the bottom is a tall black rectangle, directly above it should be the white rectangle.
To fix the interstage wrap you'd have to cut off the low section down the lowest horizontal recess line. Then line up the tunnel (half round dowel) positions with the lower wrap before using the spray adhesive. Spray and glue the low, cut off section.
Spray the upper (remaining 2/3) of the wrap. Line up the umbilical connectors. The upper part of the interstage wrap will end up rotated to the right, 1/4 turn.
There was no addendum in the instructions I received.
Notice the tunnel top on the lower left. On the upper part of the wrap, the single upper tunnel should end up above and to the right of the top of the lower left side tunnel.
There was no addendum in the instructions I received. I'll be building it as is with the umbilical connections and tunnels where they are. Unless you are a true bolt counter, I doubt anybody will notice. But as it is it isn't really correct.
EDIT: Without cutting and rotating the interstage wrap - The black paint vertical band won't end up as shown in the picture shown below left. The four Ullage motors will end up a little more to the right, not as close to the edge of the vertical black bands. One of the vertical UNITED STATES decals will have to be set over to the right, to the side of an upper tunnel.

Here's a great illustration of the wrap orientation from the Apogee Saturn V instructions.
Here's the kit interstage wrap glued in place.
When setting down the wraps, sight down the tube to be sure the tunnel tops and bottoms are in line.
You may get end lifts after the wraps have been sitting for a few hours.
TIP: Sneak some CA glue and press the ends back down. Have Q-tips handy to pick up any excess glue before it dries. Pick up the excess glue, the CA will be hard to sand when it is dry and hard.
