LyX 1.3.0 ignoring commands in layout preamble

[Patrick Hartling]

I have a LyX layout that I used with 1.1.6 to write my master's thesis, 
but it isn't working quite right with 1.3.0.  In particular, I have the 
following for the layout preamble:

Preamble
    \def\bibname{BIBLIOGRAPHY}
    [EMAIL PROTECTED]
         {\specialchapt{\bibname
            [EMAIL PROTECTED]
          [EMAIL PROTECTED]@[EMAIL PROTECTED]
               [EMAIL PROTECTED]
                \leftmargin\labelwidth
                \advance\leftmargin\labelsep
                [EMAIL PROTECTED]@code
                \usecounter{enumiv}%
                [EMAIL PROTECTED]@empty
                [EMAIL PROTECTED]@enumiv}}%
          \sloppy
          \clubpenalty4000
          [EMAIL PROTECTED] \clubpenalty
          \widowpenalty4000%
          [EMAIL PROTECTED]
         [EMAIL PROTECTED]
           [EMAIL PROTECTED]@warning{Empty `thebibliography' environment}}%
          \endlist}
    \usepackage{tocloft}
    \let\myNumberline\numberline
    \AtBeginDocument{\renewcommand\bibname{BIBLIOGRAPHY}}
    \AtBeginDocument{\renewcommand\contentsname{\centering \large TABLE 
OF CONTENTS}}
    \AtBeginDocument{\renewcommand\listfigurename{\centering \large LIST 
OF FIGURES}}
    \AtBeginDocument{\renewcommand\listtablename{\centering \large LIST 
OF TABLES}}
    \AtBeginDocument{\renewcommand{\chaptername}{}}
    \AtBeginDocument{\renewcommand{\appendixname}{APPENDIX\ }}
EndPreamble

Basically, all of this is being ignored when the document is rendered. 
Is there something I have to do to update my layout for use with 1.3.0?
