[Perlfect-search] score not shown

[Mike Schwarz]

hi 

i have a problem with score
its shown with 0 % for each result, if there are more then 2 results
if its just 1 result, it shows 100%

option for scoring is enabled in config.pl

any idea, what the problem could be?

you can see it on http://specogna.tekhosting.ch/internet/

top left, enter for example "mieter" for several results
or enter "kundschaft" for 1 result

indexing shows no error at all 
indexed sites are 52

i appreciate any help on this
thankx
