Incidentally, one way you might be able to get arXiv.org to recognise  
your LaTeX file with additional %!TEX (or any other 'nonstandard')  
directives is to add a line

%\ -*-latex-*-

at the start of the file.  This is recognised as LaTeX source by /usr/ 
share/file/magic on Leopard and probably on other systems as well.   
According to the TeXShop documentation the %!TEX lines only have to be  
within the first 20 lines of the file to be recognised.

Alternatively, you may be able to just put the %!TEX directives after  
the \documentclass at the start of the file.
