There are still a few problems.  First one is that you have two 
translations going on.  You only want to list those things in 'entities' 
that aren't already done in the escape() function already.  So get rid 
of entities, unless you come up with some other character that needs 
translating besides  ampersand, less-than, and greater-than.

Second is that you have <pre> at begin and end of file, while the latter 
should be </pre>, to close the <pre> section.

Besides that, you have lots of illegal html going on, which most browser 
will ignore.  But you might as well get it as close as you can.  Note 
that your font logic was just plain wrong.  But you don't need it, since 
it looked good when it was broken anyway.

The following produced valid xhtml, according to S3 tester, when used 
with my files.

import os,xml.sax.saxutils
import myfiles

BOILERPLATE ="""\
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>
        My Python Scripts
    </title>
</head>
<body>
"""
def sc(adir):

        dest=open('M:/scripts.html','w')
        filelist = myfiles.myfiles(adir)

        dest.write(BOILERPLATE)
        for filename in filelist:
              if os.path.isfile(filename):
                   sorce=open(filename,'r')

                   dest.write('<h1>')
                   dest.write(filename)
                   dest.write('</h1><pre>')

                   for line in sorce:
                        line=xml.sax.saxutils.escape(line)
                        dest.write(line)
                   dest.write('</pre>')
                   sorce.close()
              else:pass
        dest.write('</body></html>')
        dest.close()
