Amit,

SoO relies on VRF for its configuration.

Please see the following document:

Hello Amit,

as Edison has explained SOO is thought for VRFs in order to avoid some routing loops.

In an IPV4 only scenario you can use one or more standard BGP community to mark routes and then take decisions on this attribute.

Hope to help
