Dave, it's worth to mention what "compare appropriately" really means. 
IMHO the original poster is looking for using a filter like (radius<=400).

For this to work attribute type 'radius' has to be of syntax Integer 
(LDAP syntax with OID 1.3.6.1.4.1.1466.115.121.1.27) and defined with 
ORDERING matching rule integerOrderingMatch (OID 2.5.13.15).

Then one could query with

ldapsearch [..command-line options with host, base-DN, scope etc..] 
(radius<=400) agencyName

Ciao, Michael.
