Scrape not working consistently and as intented

Hi - I have a script where the user enters a keyword to search and the script is supposed to return the number of  "intitle:" phrase matches.

Right now the script seems to work great for results that are >10 but seems to return an empty result when <10.

if you enter           landscaper wausau      here:  
http://prontopage.net/local3b3.php

you get the results generated here:
http://prontopage.net/local3b3.php?s=landscaper+wausau&Submit=Count 

at the top of the result page you see the url:  
http://www.google.com/search?hl=en&q=intitle:%22landscaper+wausau%22 

which when followed generates a page with "3" results.  That's the number I need to pull.   $search_number should display as:
Pages Indexed: 3   (at the bottom of the screen)

If you look at the echoed data it displays
Pages Indexed:     (empty)

If you look in the echoed data you can see  
"WebResults 1 - 3 of about 3 for"    (the 3 between "about" and "for" is what I need)

Oddly a correct number is displayed if we enter:
landscaper madison

The result is 37

The url generated is http://www.google.com/search?hl=en&q=intitle:%22landscaper+madison%22

and in the echoed data you see:
Results 1 - 10 of about 37 for

and at the bottom of the page you see:
Pages Indexed: 37

That is perfect....

can someone please look at this and tell me how I might get the proper result for <10 results?

Thanks
