the first tag A0 should be primitive and not constructed instead of A0 (1010
0000) you should have 80 (1000 0000) because Stkt-Type is a primitive type
(ENUMERATED) and the tag should be followed immediately by 01 02 since your
are in an IMPLICIT tagging mode as specified at the start of the module.

I think a correct encoding would be :
000000: 30 3e 80 01 02 81 01 64 30 36 a0 19 02 02 0c 1c |0>.....d06......|

000032: 34 35 30 36 34 a0 19 02 02 0c 1c 02 01 02 02 01 |45064...........|
000048: 0a 02 01 02 04 0a 36 36 34 30 30 39 36 35 34 32 |......6640096542|
StktVarPart SEQUENCE
{
type Stkt-Type = call(2)
srv-id INTEGER = 100
ele SEQUENCE_OF

{
data Stkt-tag
{

subfeat INTEGER = 2

subtype INTEGER = 1
dump OCTET_STRING = 31.31.30.37.38.34.35.30.36.34
}
}
Stkt-ele
{
data Stkt-tag
{
feature INTEGER = 3100
subfeat INTEGER = 2
type INTEGER = 10
subtype INTEGER = 2
dump OCTET_STRING = 36.36.34.30.30.39.36.35.34.32
}
}
}
}
Maybe this will help you.
