Debian DSC patch file format has changed and not recognized by dpkg-source

For a long time I receieved some software as a patched set of files and it includes DSC file which was a text file and I run dpkg-source -x *.dsc command to extract sources. But this DSC file now is a compressed archive containing lot of folders and files and the command dpkg-source -x fails with > dpkg-source: error: syntax error in {}.dsc at line 1: line with > unknown format (not field-colon-value) How to override this error? dpkg version is 1.22.20, all archives type support is included, the distro is not Debian-based (Arch). Also in old text file the first string is Format: 3.0 (quilt) and in the new archive debian/source/format has the same 3.0 (quilt) string.
