Ulimit is implemented by the shell, and thus the options that are recognised, and thus the allowable order of the options, is up to each shell. Kshell allows either ulimit -Hc value or ulimit -cH value while bash seems only to allow -Hc value (probably because it assumes any characters following the 'c' without a space are to be interpreted as the value).
So the real question is what is your underlying shell that is interpreting your script? If it is bash, then you'll have to ensure that ulimit -Hc is what is coded. If you are using Kshell, then either format should work. I cannot say how other shells will react as I don't have any installed anywhere to test.

ulimit
ULIMIT(3) BSD Library Functions Manual ULIMIT(3)
NAME
ulimit -- get and set process limits
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <ulimit.h>
long
ulimit(int cmd, ...);
DESCRIPTION
The ulimit() function will get and set process limits. Currently this is limited to the maximum file size. The cmd argument is one of the
following:
UL_GETFSIZE will return the maximum file size in units of 512 blocks of the current process.
UL_SETFSIZE will attempt to set the maximum file size of the current process and its children with the second argument expressed as a long.
RETURN VALUES
Upon successful completion, ulimit() returns the value requested; otherwise the value -1 is returned and the global variable errno is set to
indicate the error.
ERRORS
The ulimit() function will fail if:
[EINVAL] The command specified was invalid.
[EPERM] The limit specified to ulimit() would have raised the maximum limit value, and the caller is not the super-user.
SEE ALSO
getrlimit(2)
STANDARDS
The ulimit() function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
The ulimit() function first appeared in FreeBSD 5.0.
BUGS
The ulimit() function provides limited precision for setting and retrieving process limits. If there is a need for greater precision than
the type long provides, the getrlimit(2) and setrlimit(2) functions should be considered.
