Yup, CISCO-SWITCH-QOS-MIB::csqIfStatsDropPkts should do the trick.
Beware that counters are only cleared on reboot, not with "clear
counters". The index for the list is plain ifIndex.

Switch#show interfaces GigabitEthernet1/5 | incl Total output drops
  Input queue: 0/2000/0/0 (size/max/drops/flushes); Total output drops: 1802440
Switch#show queueing interface GigabitEthernet1/5 | begin ^  Packets dropped on Transmit
  Packets dropped on Transmit:
    BPDU packets:  0

    queue              dropped  [cos-map]
    ---------------------------------------------

    1                       25  [0 1 ]
    2                  1802415  [2 3 4 ]
    3                        0  [6 7 ]
    4                        0  [5 ]

  Packets dropped on Receive:
    BPDU packets:  0

    queue              dropped  [cos-map]
    ---------------------------------------------
    1                        0  [0 1 2 3 4 5 6 7 ]
Switch# show snmp mib ifmib ifindex GigabitEthernet1/5
Interface = GigabitEthernet1/5, Ifindex = 5
Switch#

And on a management station:

$ snmpbulkwalk <options> Switch CISCO-SWITCH-QOS-MIB::csqIfStatsDropPkts.5
CISCO-SWITCH-QOS-MIB::csqIfStatsDropPkts.5.inbound.1.1 = Counter64: 0
CISCO-SWITCH-QOS-MIB::csqIfStatsDropPkts.5.outbound.1.1 = Counter64: 25
CISCO-SWITCH-QOS-MIB::csqIfStatsDropPkts.5.outbound.2.1 = Counter64: 1802415
CISCO-SWITCH-QOS-MIB::csqIfStatsDropPkts.5.outbound.3.1 = Counter64: 0
CISCO-SWITCH-QOS-MIB::csqIfStatsDropPkts.5.outbound.4.1 = Counter64: 0
$

This is from a 6500 running SXI but I assume 7600 SRx is the same.
