Works on command line but not in script
OSX 10.9

I am building a script that evaluates the difference between 2 files. Here is a command that does not work transparently.

Running this command in Terminal yields great results; however when I put that line in a .sh script, I get the errors shown below. Am I doing something silly?

In Terminal:
Code:
comm -23 <(sort ~/Desktop/t1.txt) <(sort ~/Desktop/t2.txt)

Outputs (difference between 2 files): 
change
hello mate
hello mate = 3

In Script (by itself):
Code:
#!/bin/bash
comm -23 <(sort ~/Desktop/t1.txt) <(sort ~/Desktop/t2.txt)

Outputs: 
line 2: syntax error near unexpected token `('
line 2: `comm -23 <(sort ~/Desktop/t1.txt) <(sort ~/Desktop/t2.txt)'

tic

tic(1)							      General Commands Manual							    tic(1)

NAME

       tic - Translates terminfo files from source to compiled format

SYNOPSIS

       tic [-v[number]] [-c] [file...]

       The tic command translates terminfo files from the source format into the compiled format.

OPTIONS

       Checks  the file for errors only.  Errors in the use= field are not detected.  Writes trace information on the progress of the tic command.
       The number parameter is an integer, from 0 to 8, that increases the level of verbosity.	If number is omitted, the default is 1.

DESCRIPTION

       If a file is not specified, the tic command reads standard input.

       The tic command places the results in the /usr/share/lib/terminfo directory.  If the TERMINFO environment variable is set, the results  are
       placed there instead of in /usr/share/lib/terminfo.

       The  tic  command compiles all terminfo descriptions in the file or files specified by the file variable. When the tic command finds a use=
       field, it searches first the current file, then reads in the binary from /usr/share/lib/terminfo to complete the entry.	If the environment
       variable TERMINFO is set, that directory is searched instead of /usr/share/lib/terminfo.

       The  size  of a compiled entry cannot exceed 4096 bytes and the name field cannot exceed 128 bytes.  Terminal names exceeding 14 characters
       are truncated to 14 characters and a warning message is printed.

ENVIRONMENT VARIABLES

       The following environment variables affect the behavior of tic: Causes the command to behave as a System V command if  the  value  of  this
       environment  variable  is  set  to  SVR4  or  svr4.  The options designated by [SVR4]  are honored while identical non-System V options are
       ignored. Command output and error messages  also follow System V conventions.

FILES

       Terminal information database.
