[aquaria] [PATCH] Fix global references in scripts

[Andrew Church]

Found a couple of global variable references I overlooked during the
script updates, so here's a fix.

FWIW, I wrote a little "lint"-like script to report improper accesses to
global variables from scripts, but I'm not sure if there's a good place
for it in the repository -- Ryan, any thoughts?  I could always just
post it to the list, I guess.
