I get your result when the input file contains Mac linebreaks[*]. Change the
input file's linebreaks to unix linebreaks[*], and the below works fine:

set input to quoted form of POSIX path of (choose file)
do shell script "grep '|(TRAV)|' " & input

The clue was given by using grep's -n flag, which prints line numbers for
every line found. With the Mac line endings in the input file, grep printed
only a single line number, indicating that it considered the file to contain
a single line. And since that single line does contain the needle, it was
given as the result.

[*] With "Mac linebreaks" and "unix linebreaks" I'm using BBEdit/TextWrangler
terminology.
