SQL Compare and Perforce with revision switch

Hi, We switch from Vault to Perforce (P4V), originally this script work fine with Vault, since we are on Perforce we have this error message :
Error : Only head revisions are available for command-line base source control systems
We try to compare two database, here is the script :
"C:\Program Files (x86)\Red Gate\SQL Compare 10\sqlcompare.exe" /s1:PROD /db1:CurrentDev /r1:1287924 /s2:PROD /db2:empty /Options:iu,Default,DoNotOutputCommentHeader,IgnoreWhiteSpace /Force /sf:"C:\OUT.SQL"
Is there a special configuration to setup SQL Compare with Perforce for supporting the compare option with a revision number?
fyi : when I replace r1:1287924 by r1:HEAD it work fine.
Thanks,
Bernard
