LSAC didn't assign the June 2007 LSAT a number when they released it. It is an official past LSAT just like the numbered tests. Only a few preptests aren't identified by a sequential number. Powerscore's LSAT Publication Identifier is a handy reference to see where these fit in the numbered list.

I'm interested if this is still open. I work full time also. I can relate. I'm on EST.
