regexp = "##[[:space:]]*([0-9]{2-3})";

If you need to find all, you do it in a loop:
<cfscript>
regexp = "##[[:space:]]*([0-9]{2-3})";
results = ArrayNew(1);
start = 1;
while(true){
stTmp = REFindNoCase(regexp,str,start,true);
if(stTmp.pos[1]){
ArrayAppend(results,Mid(str,stTmp.pos[2],stTmp.len[2]));
start = stTmp.pos[1] + stTmp.len[1];
}
else break;
}
</cfscript>
Probably you want to make sure that the character after the 2-3 digits
is not a digit. If so, modify the regexp to
regexp = "##[[:space:]]*([0-9]{2-3})([^0-9]|$)";
On CFMX you could use negative lookahead:
regexp = "##\s*(\d{2,3})(?!\d)";
