Seemlinly simple problem here. I've got a 5400 as our core switch and have a 3500 attached to one of the ports. I was adding a vlan, 103, and configuring it across the switches. The 3500 was on port F10 with a few vlans already setup. Added 103 as tagged and configured it on the 3500 as such. No traffic passed between them on that vlan. I tried a few different things on the 3500 with no luck. Out of desparation I moved the 3500 to port F11 on the 5400 and configured it the same as F10 and it all starts magically working. Thoughts? Anything no the config print out that could cause the issue? Here's the config of the 5400:

Truly hard to understand the root cause of your issue...but, looking at your Switch running software version (K.15.02.0005), as it appears on reported configuration:

a thing is pretty clear: your Switch is running an almost 7 years old firmware (K.15.02.0005 was released on October 2010)...please correct me if I'm wrong here (a show flash and show version would clear things up with that regard)...so anything "strange" is truly possible...especially considering how many releases (K.15.xx and newer K.16.xx) were published in that very long timeframe.

I suggest you to revise old Release Notes (of K.15.04 or K.15.06. software branches, as example) - it's a time consuming task - to look for if a similar issue involving VLAN tagging was found and eventually fixed...but then, if you find it, don't limit yourself to upgrade to the nearest (old) fixing version...instead go ahead - that's a relatively fast procedure - and decide to keep your Switch software current (as example updating it to latest K.15.18 or better to latest K.16.02).
