Yes, the element order counts. You can test the current validation issue with:
ffprobe -f lavfi mandelbrot -show_versions -show_streams -of xml=q=1:x=1 -noprivate > test.xml
xmllint --noout --schema ffprobe.xsd test.xml
which gives an error on line 16 since <streams> occurs after <library_versions>
test.xml:3: element program_version: Schemas validity error : Element 'program_version', attribute 'compiler_ident': The attribute 'compiler_ident' is not allowed.
test.xml:3: element program_version: Schemas validity error : Element 'program_version': The attribute 'compiler_type' is required but missing.
test.xml:3: element program_version: Schemas validity error : Element 'program_version': The attribute 'compiler_version' is required but missing.
test.xml:16: element streams: Schemas validity error : Element 'streams': This element is not expected.
test.xml fails to validate
