I don't use texify (I personally prefer to write Makefiles, rather than relying on magic commands), but I think you don't understand how errorlevel works - it is cumulative. If texify returns exit *code* 1, then you will have errorlevel 1 and errorlevel 0. If you want to use the actual exit code, you need to use %ERRORLEVEL% which is a number, e.g.

if %errorlevel% equ 1 goto lab1

Though I have no idea if texify actually sets exit codes on error (you can tell this by using echo %ERRORLEVEL%).

HTH,
