There was a thread this week related to this issue. With KDE 3.2 it will be 
possible with the help of KMimeType::findFormatByFileContent(const QString&) 
method. I use:
   bool text = false;
   KMimeType::Format f = KMimeType::findFormatByFileContent(url.path());
   if (f.text && f.compression == KMimeType::Format::NoCompression)
       text = true;

If you want this in the upcoming KDE 3.1.1,  "backport" that method locally 
for your application. I'm afraid there is no easy way for KDE 3.1 or earlier 
versions.

If you would like to detect only shell scripts, you may use the other 
KMimeType methods and check for application/x-shellscript.
