Problem when I try to overwrite with Python

Hi,

I create a geoprocessing model that basically compare two features class and if it find a new record it write it to a feature class. we export this model to python script so this process could run every day at 6 pm automatically. when we run this model in model builder it works just find but when we run it after export it i got an error saying that some layers already exist but thats why we are overwriting the information.

this is the script and we added two lines to force it to overwrite

Attachment 19545
Attachment 19546

and when we run this process from Python this is the error

As you can see we have a true, that means that the command line for overwrite is working

Does any one has any idea what could be happening? why is working find if I run the model but after exporting to python we got that error?
