Hi Vlad,
there is no mystery in these numbers indeed.

GOMZ have produced Leningrad cameras with 2 screws up to 1958. All these cameras have 2-digits date prefix in the serial number, right?
To participate in famous Brussel's Fair (1958), GOMZ have produced a limited quantity of Leningrad bodies with 4 screws already. These cameras are unique, since fitted with GOMZ origin Jupiter-8 lenses. The serial number system was limited, since only 9.999 copies of Leningrad could be released obviously (6-digits serial number, 2-digits date prefix "58", so only 4 digits left ...). After the total amount of the released cameras have exceeded 10.000 units, GOMZ have changed the s/n coding system again. The new system starts from #000.001 and has no date prefix in the number.
So all the cameras from late 1958 up to 1960 can be find with "zero" as the 1st character. Though the big majority of these bodies have 4 screws on the frontplate, very few cameras can be found with old stock 2 screws yet (my #001058 for example).
Serial numbers of Leningrad were changed in 1960 again. These very few cameras have 2-digits date prefix "60", but are very rare to find nowadays. All cameras from 1961 have 6-digits serial number with 2-digits date prefix again...
The same story in 1963. After the total amount have exceeded 9.999 copies in 1963, LOOMP have released Leningrad with new s/n coding system again ...

. These cameras came into the market with s/n "3xx.xxx", i.e 1-digit date prefix ("3" stands for 1963). Such a big amount of cameras per year was never reached again, so cameras released in 1964-1965 have standard s/n with 2-digits date prefix again...
Hope you will find my explanation useful.
