If I skip the beginning of a map, the audio desyncs from the actual map and everything is played an indeterminate bit behind the actual audio, making most maps unplayable. However, if I do not skip, the maps play perfectly normal.

The skip button is also acting strangely and sometimes requires several taps to actually do anything in the first place.

This is on the 3.1.2 firmware jailbroken by blackra1n RC2 on a 3G itouch 8gb

I can actually confirm this on my 3.1.1 FW iPod Touch 2G.

This is easy to replicate but not so easy to fix. To do so, the way audio is being handled needs to be substantially changed.
