IANA will officially assign numbers once the I-D has progressed to standard status. They'll show up here:

http://www.iana.org/assignments/tls-parameters/tls-parameter...

In the mean time, the I-D does contain the requested values in section 3:

    TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305   = {0xTBD, 0xTBD} {0xCC, 0xA8}
    TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305 = {0xTBD, 0xTBD} {0xCC, 0xA9}
    TLS_DHE_RSA_WITH_CHACHA20_POLY1305     = {0xTBD, 0xTBD} {0xCC, 0xAA}

    TLS_PSK_WITH_CHACHA20_POLY1305         = {0xTBD, 0xTBD} {0xCC, 0xAB}
    TLS_ECDHE_PSK_WITH_CHACHA20_POLY1305   = {0xTBD, 0xTBD} {0xCC, 0xAC}
    TLS_DHE_PSK_WITH_CHACHA20_POLY1305     = {0xTBD, 0xTBD} {0xCC, 0xAD}
    TLS_RSA_PSK_WITH_CHACHA20_POLY1305     = {0xTBD, 0xTBD} {0xCC, 0xAE}

(the ones in the latter brackets) and IANA is very likely to use those. There's always a bit of a chicken and egg race condition here, usually resolved with a friendly mail to the IANA administrator.
