1. You should move the submit's onclick event to the form's onsubmit event.
You can't be sure that clicking the submit button will be the only way a
form will be submitted. Removing events from the markup would be nice as
well, but it works for now.

2. You'll need another hidden input:

<input type="hidden" name="saveScrollTop" value="">

...and JS to save:

if(theform.mytext.scrollTop)theform.saveScrollTop.value=theform.mytext.scrollTop;

...and load:

if(theform.saveScrollTop.value)theform.mytext.scrollTop.value=theform.saveScrollTop.value;

3. This should provide bare functionality; it won't catch exceptions if
the browser doesn't like you setting scrollTop or anything like that, but
this might get it working.
