Jumi variable not available in included script

Question

I am using joomla 3.2 with jumi 3, here is a sample of how I call my script via jumi

{jumi [myscript.php] [foo] [bar]}

here is myscript.php

<?php
    echo $jumi[0];
    echo $jumi[1];
?>

above script is successfully able to print the values as foo & bar

but if I modify the same to include another script ans try to get the variables in that script then it does not have any value

here is new myscript.php

<?php
    include 'foobar.php';
?>

foobar.php

<?php
    echo $jumi[0];
    echo $jumi[1];
?>

this fails to print the values. help me find if I am missing something
