Sorting based on the second field

Oracle Enterprise Linux 6

This is my file. Two fields separated by space
Code:
$ cat testfile.txt
MARCH9 MARCH4
MARCH1 MARCH5
MARCH2 MARCH326
MARCH821 MARCH7
MARCH6 MARCH2
$
$

The following numeric sort, based on the first field's 6th character works as expected.
Code:
$
$ sort -n -k  1.6 testfile.txt
MARCH1 MARCH5
MARCH2 MARCH326
MARCH6 MARCH2
MARCH9 MARCH4
MARCH821 MARCH7
$

But the following attempt to sort the lines based on the second field's numeric character doesn't seem to work.
--- In the below example for "-k 2.6" , 2 denotes second field, 6 denotes the character based on which sort should happen (I have a numeric sort here)
Code:
$
$ sort -n -k  2.6 testfile.txt
MARCH1 MARCH5
MARCH2 MARCH326
MARCH6 MARCH2
MARCH821 MARCH7
MARCH9 MARCH4

NAME
slapo-valsort - Value Sorting overlay to slapd SYNOPSIS
/etc/ldap/slapd.conf DESCRIPTION
The Value Sorting overlay can be used with a backend database to sort the values of specific multi-valued attributes within a subtree. The sorting occurs whenever the attributes are returned in a search response. Sorting can be specified in ascending or descending order, using either numeric or alphanumeric sort methods. Additionally, a "weighted" sort can be specified, which uses a numeric weight prepended to the attribute values. The weighted sort is always performed in ascending order, but may be combined with the other methods for values that all have equal weights. The weight is specified by prepending an integer weight {<weight>} in front of each value of the attribute for which weighted sorting is desired. This weighting factor is stripped off and never returned in search results. CONFIGURATION
These slapd.conf options apply to the Value Sorting overlay. They should appear after the overlay directive. valsort-attr <attribute> <baseDN> (<sort-method> | weighted [<sort-method>]) Configure a sorting method for the specified attribute in the subtree rooted at baseDN. The sort-method may be one of alpha-ascend, alpha-descend, numeric-ascend, or numeric-descend. If the special weighted method is specified, a secondary sort-method may also be specified. It is an error to specify an alphanumeric sort-method for an attribute with Integer or NumericString syntax, and it is an error to specify a numeric sort-method for an attribute with a syntax other than Integer or NumericString. EXAMPLES
database bdb suffix dc=example,dc=com ... overlay valsort valsort-attr member ou=groups,dc=example,dc=com alpha-ascend FILES
