I assume that by "create" you mean the mtime shown in your ls output. You can use stat and localtime to get what you want. 

while (<*Dec2003*.txt>) {    # this is a glob
    if ( (localtime( (stat)[9]))[4] == 11 ) {
        # open $_ and process it
    }
}

Update: Not_a_Number++ is correct. Repaired.
