Hmmm...maybe you need a new enough tee also:
SYNOPSIS
tee [OPTION]... [FILE]...
DESCRIPTION
Copy standard input to each FILE, and also to standard output.

Yep, those should work also. The named pipe would work too, if you did
something like:
mkfifo p1 p2 p3
bzcat data*bz2 | tee p1 | tee p2 > p3 &
perl script1.pl < p1
perl script2.pl < p2
perl script3.pl < p3
(make sure and background or run in another terminal the bzcat.)
