sorting ASCII string containing numbers

I have the following output where I need to sort the second column numerically (starting with IBMULT3580-TD10 and ending in IBMULT3580-TD123)

Code:

Drv DriveName       
  0 IBMULT3580-TD13 
  1 IBMULT3580-TD18 
  2 IBMULT3580-TD14 
  3 IBMULT3580-TD10 
  4 IBMULT3580-TD11 
  5 IBMULT3580-TD17 
  6 IBMULT3580-TD117
  7 IBMULT3580-TD121
  8 IBMULT3580-TD15 
  9 IBMULT3580-TD112
 10 IBMULT3580-TD115
 11 IBMULT3580-TD111
 12 IBMULT3580-TD116
 13 IBMULT3580-TD12 
 14 IBMULT3580-TD113
 15 IBMULT3580-TD19 
 16 IBMULT3580-TD118
 17 IBMULT3580-TD16 
 18 IBMULT3580-TD123
 19 IBMULT3580-TD119
 20 IBMULT3580-TD120
 21 IBMULT3580-TD110
 22 IBMULT3580-TD114
 23 IBMULT3580-TD122

I'm trying to apply the sort, and the output is getting sorted, but not numerically:

Code:

`some_command` |sort -k 2

  3 IBMULT3580-TD10 
 21 IBMULT3580-TD110
 11 IBMULT3580-TD111
  9 IBMULT3580-TD112
 14 IBMULT3580-TD113
 22 IBMULT3580-TD114
 10 IBMULT3580-TD115
 12 IBMULT3580-TD116
  6 IBMULT3580-TD117
 16 IBMULT3580-TD118
 19 IBMULT3580-TD119
  4 IBMULT3580-TD11 
 20 IBMULT3580-TD120
  7 IBMULT3580-TD121
 23 IBMULT3580-TD122
 18 IBMULT3580-TD123
 13 IBMULT3580-TD12 
  0 IBMULT3580-TD13 
  2 IBMULT3580-TD14 
  8 IBMULT3580-TD15 
 17 IBMULT3580-TD16 
  5 IBMULT3580-TD17 
  1 IBMULT3580-TD18 
 15 IBMULT3580-TD19

I tried adding -n but it produces a rather weird output, seemingly in random order. Any suggestions how to sort this string numerically? I can't figure it out from the sort man page. TIA!
