Second run with debug output spotted problem on this command:

nice -n 0 mkvmerge -o "/tmp/dts_eng.new.mkv" --compression :none "dts_eng.mkv" --track-name 0:"Оригинал" --compression 0:none "/tmp/dts_eng.ac3"

mkvmerge v2.3.0 ('Freak U') built on Sep  9 2008 17:43:13
Error: Invalid track ID specified in '--compression :none'.

After intuitive command line fixing got this:
